is carbon an element

By vaporizing graphite with lasers, the scientists created a mysterious new molecule made of pure carbon, according to the American Chemical Society. It is called cognitive dissonance. Ed. It is evident the designers focused upon the air temperatures because of the tradition that air temperature had been from the beginning been accepted as a proxy for the earth’s surface temperature in the S-B radiation law. Carbon exists in va… Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. Hi James, You have just made my point. Carbon is an element with atomic number 6. temperature would be 33C less if not for the greenhouse gases of the atmosphere.. And based upon the lack of comments relative to the two posting to which I have directed attention, who can claim to have studied the data which was not available to Arrhenius and needed by him to properly do his radiation balance calculation. Carbon in the form of coal is an important fuel The detailed knowledge from these measurements is embedded in the MODTRAN and HITRAN databases, which present in great detail how much IR is absorbed at different wavelengths under different atmospheric conditions. #l: How is C02 dispersed globally and equally important, at what altitudes. Just How Accurate Are Weather And Climate Measurements? Diamond is transparent. You have three major types of carbons: graphite, diamond, and the fullerenes. We have been threatened lest we use up our Carbon Footprint. When my essays are posted there are usually 20 fewer comments, if there are any, than there are now. These hydrocarbons, extracted naturally as fossil fuels … In microcrystalline and nearly amorphous form, it is used as a black pigment, as an adsorbent, as a fuel, as a filler for rubber, and, mixed with clay, as the “lead” of pencils. Elemental carbon is nontoxic. Carbon has a valency of four, … All the trash that is trumpeted about emissions of Carbon Dioxide is just that – trash! Carbon products are obtained by heating coal (to give coke), natural gas (to give blacks), or carbonaceous material of vegetable or animal origin, such as wood or bone (to give charcoal), at elevated temperatures in the presence of insufficient oxygen to allow combustion. It is understood that the max. Note that this may not be a steady-state case — I just bring it up as an understandable example. Carbon was officially classified as an element near the end of the eighteenth century. In 1787, four French chemists wrote a book outlining a method for naming chemical substances. Is Sustainable Energy Even Possible Globally? Interesting information about the ‘absorption’ of IR radiation during different atmospheric conditions. Most consumers are familiar with the element, along with numerous forms in which it ap… 400ppm of CO2 absorb virtually all 15um radiation within one meter of travel in air (at STP). Since there are now some nine billion humans living on this Planet Earth and since they are exhaling Carbon Dioxide at the rate of circa 20 breaths a minute, to call this exhalation a pollutant is not just a misnomer but also a crime against humanity itself. Two postings (https://principia-scientific.com/record-temperature-result-of-cloud-revised-updated/) and (https://principia-scientific.com/the-corvallis-or-uscrn-site-a-natural-laboratory/) review actual data from NOAA’s two projects (SURFRAD and USCRN). “And this is true even with Atlanta’s greater cloud cover, which you mention, but don’t consider its cooling effect”. June 40/24 30/18 Air at 40C and 20% relative humidity (typical for Phoenix in the summer) has a moist enthalpy of 64.5 kJ/kg. Synthetic diamonds are now manufactured in several countries and are being used increasingly in place of natural materials as industrial abrasives. Coke and charcoal are nearly pure carbon.) Principia Scientific International (PSI) is a not-for-profit community interest association. Say these Physicists, since Carbon Dioxide absorbs infrared and be it said emits it, therefore it follows that these molecules high up in the atmosphere get hot, stay hot and prevent heat ebbing away. At high temperatures carbon binds with oxygen to form carbon monoxide (CO) or dioxide (CO2). C02 @ .04% with CH4 @ .00018 – .04018 total. So why do I labour the point? I am aware that relative humidity is not the same as humidity (details of which I have not found). Cheers. Two of its well-defined forms, diamond and graphite, are crystalline in structure, but they differ in physical properties because the arrangements of the atoms in their structures are dissimilar. The US Air Force has spent many millions of dollars over decades measuring the IR absorption/transmission in the atmosphere under a wide variety of conditions because this knowledge is critical to the success of its heat-seeking missiles, which track IR emissions from planes and the like. Get a Britannica Premium subscription and gain access to exclusive content. In 1961 the isotope carbon-12 was selected to replace oxygen as the standard relative to which the atomic weights of all the other elements are measured. September 38/24 28/17 They dare not sue, because to do…, Does this come as any surprise? The primary source of diamonds is a soft bluish peridotic rock called kimberlite (after the famous deposit at Kimberley, South Africa), found in volcanic structures called pipes, but many diamonds occur in alluvial deposits presumably resulting from the weathering of primary sources. One of the most important chemical elements is carbon. Graphite cannot be melted but can be sublimed at 3,650°C and in any form, Carbon is a solid at room temperature. Atomic form of carbon is very short lived and readily stabilizes in multi-atomic configurations. Here is my question. Carbon stars are stars whose atmosphere has more carbon than oxygen. Carbon is the fourth most abundant element in the universe behind Hydrogen, Helium and Oxygen. Your answer is correct Ed, but that is a LABORATORY numer, not the real world. The first one seems to have no comments section but I will ask a question at the second one. Lessons From A Chicken Wire Stack On Moon, Global Cooling: Beware the Snowman Cometh. The two most familiar forms of carbon—diamond and graphite—differ greatly because of the arrangement of their atoms. The volatile by-products are recovered and used separately. For example, air at 30C and 80% relative humidity (typical for Atlanta in the summer) has a moist enthalpy of 85.8 kJ/kg (relative to dry air at 0C). GRAVISPHERES: What’s the matter with Dark Matter? Carbon, an element of prehistoric discovery, is very widely distributed in nature. Not only that, it has an Atomic number, which is 6. Molecules of fullerene show promise in a range of applications, including high-tensile-strength materials, unique electronic and energy-storage devices, and safe encapsulation of flammable gases, such as hydrogen. Carbon is a really cool element. Because it conducts electricity but does not melt, graphite is also used for electrodes in electric furnaces and dry cells as well as for making crucibles in which metals are melted. Two fullerene structures: an elongated carbon nanotube and a spherical buckminsterfullerene, or “buckyball.”. Carbon has atomic mass 12 and atomic number 6. What does that mean? The most important radioisotope is 14 C, with a half-life of 5.6 × 10 3 years. This cycle is extremely complex, and it illustrates the interconnection between organisms on Earth. Spheroidal, closed-cage fullerenes are called buckerminsterfullerenes, or “buckyballs,” and cylindrical fullerenes are called nanotubes. Yes, it is a fact. An observed fact is the downwelling IR is seldom ever greater than the upwelling radiation from the surface. The fact that the molecules of the entire Greenhouse Gases are just one in one hundred, and that at altitude they are farther and farther apart, with ‘nothing’ in between the molecules, means that the whole idea of a Greenhouse block suspended high up in the Troposphere is just a non-starter. Long before you get to 400ppm, you will see dramatic differences in the transmission of visible light, even over a fraction of a meter. (source; Wiki, I.P.C.C. PRINCIPIA SCIENTIFIC INTERNATIONAL, legally registered in the UK as a company incorporated for charitable purposes. Thanks Jerry for your comments. Humidity is not the same as relative humidity. Aha! Charcoal is used as an absorptive and filtering agent and as a fuel and was once widely used as an ingredient in gunpowder. Liberal politicians and thousands of camp followers demand that we should be Carbon free. #2: My understanding is that C02 re-radiates heat 360 degrees. So maybe this comment will be read by more than there is evidence that my previous essays have. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. With hot oxidizing agents [Potassium nitrate (KNO­3) and Nitric acid (HNO3)], Metilic acid C6(CO2H)6 is obtained. A few ppm of absorptive molecules in water provide significant attenuation in just a few tens of millimeters. The answer is simple – you have it in one. August 40/27 31/20 From the Latin word carbo:charcoal. You may have heard that carbon is the element of life. November 25/10 18/5 Graphite, on the other hand, is a soft slippery solid that is a good conductor of both heat and electricity. Graphite occurs naturally in many areas, the deposits of major importance being in China, India, Brazil, Turkey, Mexico, Canada, Russia, and Madagascar. So your quantitative argument is fundamentally flawed from the beginning. While is did proofread this comment and corrected several mistakes I missed that ‘briefs’ in the first sentence should have been ‘beliefs’. Anybody, just anybody these days can look it up in an instant on a smartphone, on a computer. But I would guess the studies do not question about what happens to the IR radiation that is absorbed. Take 1 liter of water in a glass container. Is that a scientific conclusion? Head Office: 27 Old Gloucester Street, London WC1N 3AX. Fullerene was serendipitously discovered in 1985 as a synthetic product in the course of laboratory experiments to simulate the chemistry in the atmosphere of giant stars. Carbon is indeed an element, number 6 on the periodic table. Subsequently, chromium, manganese, cobalt, nickel, and tantalum were substituted for iron. A carbon atom is capable of combining with up to four other atoms (tetravalent), including other carbon atoms; it is this property that allows so many compounds to be formed. July 41/28 32/21 From the moment a baby is born into this world until the time of his or her final breath, this being is inhaling Oxygen and mixing it with Carbon, in order to produce energy, and exhaling a clear transparent gas called Carbon Dioxide. – 9B population seems high. An abundant nonmetallic, tetravalent element, carbon has several allotropic forms: diamonds (hardest known mineral). Don't worry about the last one really. Anyone can look it up, as I just have. In the crust of Earth, elemental carbon is a minor component. But is Atlanta’s atmosphere’s water vapor significantly greater than that of Phoenix as it implied on the basis of the yearly average relative humidity data ? Why is carbon an important element? And of course, a purpose of these natural laboratories was to verify the average temperature (to the hundredths or even thousands of a degree) of the earth being measured from satellite platforms in space. Isolated finds around the world in regions where no sources are indicated have not been uncommon. So I question why these people have not expressed their beliefs relative to these measured surface temperatures which are reviewed in these two postings. However, if I am just shining a flashlight at you, the fact that you are shining a brighter flashlight at me in no way diminishes how you perceive my light. By the way, the 1% trace gas component is overwhelmingly argon, which is completely transparent to IR. This means carbon is an element. Carbon is made up of just one type of atom. Then why would any CO2 that absorbs IR; which is then thermalized; and re-radiated at other wavelengths; not be “jammed” by the stronger outgoing IR from earth? Q-carbon is also synthetic, but scientists have speculated that it could form within the hot environments of some planetary cores. Biologically, carbon holds a significant position and is part of all living systems. Located between boron (B) and nitrogen (N), it is a very stable element. They even form a barrier called the Greenhouse Effect. ), might be useful to confirm this assertion. Atomic number, 6; atomic weight, 12.011. Which of its properties do you like the most? Carbon is characterized as the 4th most abundant element in the universe and the 15thmost abundant element in the Earth’s crust. February 22/9 14/2 Yet my good, no doubt well meaning, friends, wish to be Carbon free. Every carbon atom is covalently bonded at the four corners of the tetrahedron to four other carbon atoms. Coal and coke, for example, are used extensively as fuels. Phoenix latitude 33.4: altitude 1106 feet Graphite is used as a lubricant. PRINCIPIA SCIENTIFIC INTERNATIONAL is legally registered in the UK as a company incorporated for charitable purposes. The word carbon probably derives from the Latin carbo, meaning variously “coal,” “charcoal,” “ember.” The term diamond, a corruption of the Greek word adamas, “the invincible,” aptly describes the permanence of this crystallized form of carbon, just as graphite, the name for the other crystal form of carbon, derived from the Greek verb graphein, “to write,” reflects its property of leaving a dark mark when rubbed on a surface. Carbon is the cosmic product of the “burning” of helium, in which three helium nuclei, atomic weight 4, fuse to produce a carbon nucleus, atomic weight 12. Is that a fact? Cheers. So there is no doubt about it at all. . It is not an opinion. C, a chemical element of group IV of Mendeleev’s periodic system. (Coals are elemental carbon mixed with varying amounts of carbon compounds. Only hydrogen, helium, oxygen, neon, and nitrogen are atomically more abundant in the cosmos than carbon. It appears in climate-warming debates, but it doesn’t seem to be really proven by science. March 25/11 19/6 Elemental carbon exists in several forms, each of which has its own physical characteristics. You wrote: “When Feynman (and others) talk about induced or stimulated emission, they are talking about phenomena such as fluorescence, which are not relevant here.” Long ago Newton wrote (The Principia as translation by Motte): “Therefore to the same natural effects we must, as far as possible, assign the same causes. Ring in the new year with a Britannica Membership, https://www.britannica.com/science/carbon-chemical-element, h2g2 - Carbon and its Inorganic Compounds, carbon - Children's Encyclopedia (Ages 8-11), carbon - Student Encyclopedia (Ages 11 and up). Average max/min temperatures Phoenix Atlanta It is true that Nitrogen and Oxygen, which together comprise 99{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of the atmosphere, are transparent to infrared radiation, whereas the Greenhouse gases are opaque, so a bizarre and totally illogical conclusion is reached that Greenhouse gases cause warming. Thansk you for your work on the possible effect of clouds on surface temperatures at USCRN sites. Hence, the maximum possible downwelling IR at Atlanta is limited by its surface’s lower temperatures even if the water vapor content of its atmosphere might be greater. Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen.(Wikipedia). Funny! January 20/7 12/0 They are two separate processes. Since there is also a well-known Carbon Cycle, where we know that green plants feed on Carbon Dioxide and produce Oxygen as a by-product for all mankind to breathe, it must surely be the most ridiculous error ever to have been perpetrated. Atlanta is partly cloudy year round. “Thus, Einstein assumed that there are three processes: an absorption proportional to the intensity of light, an emission proportional to the intensity of light, called induced emission or sometimes stimulated emission, and a spontaneous emission independent of light.” Hence, I understand that the straight line IR radiation that is absorbed (or scattered by ‘cloud’ droplets) is given a ‘new’ direction by a scattering phenomenon or by the induced emission which follows the absorption which is proportional to the intensity of this straight line being emitted from a small, hot, surface (of small volume of a very hot gas whose water vapor composition is far greater than that of the surrounding atmosphere). Updated September 07, 2018 Carbon is the element with atomic number 6 on the periodic table with symbol C. This nonmetallic element is the key to the chemistry of living organisms, primarily due to its tetravalent state, which allows it to form four covalent chemical bonds with other atoms. For the last two decades we have all been bombarded by voices calling for a Carbon Free environment. Varying the number of electrons in an atom of an element produces ions. Three isotopes occur naturally, C and C being stable, while C is a radionuclide, decaying with a half-life of about 5,730 years. It exists in … Carbon is most commonly obtained from coal deposits, although it usually must be processed into a form suitable for commercial use. However, carbon compounds (i.e., carbonates of magnesium and calcium) form common minerals (e.g., magnesite, dolomite, marble, or limestone). It belongs to group 14 of the periodic table. Modern carbon chemistry dates from the development of coals, petroleum, and natural gas as fuels and from the elucidation of synthetic organic chemistry, both substantially developed since the 1800s. Carbon is a very important chemical element, with a chemical symbol of C.All known life on Earth needs it. Although widely distributed in nature, carbon is not particularly plentiful—it makes up only about 0.025 percent of Earth’s crust—yet it forms more compounds than all the other elements combined. Carbon makes up only about 0.025 percent of Earth's crust. Furthermore, through some obscure references to the work of Svante Arrhenius, some people have been persuaded that the Earth is getting hotter and hotter, owing to the presence of Carbon Dioxide in the Atmosphere, even though it is only a trace gas at 0.04{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of the whole.
