Each of the 13 elements has their own unique physical and chemical properties. Two are considered here: chlorine(I) oxide, Cl 2 O, and chlorine(VII) oxide, Cl 2 O 7. A)Antimony B)Krypton C)Gold D)francium. The state the water is in depends upon the temperature. 18. An atom of Mercury has 120 neutrons. What element is in group 7 and has 30 neutrons. It is the lightest element. As a group, halogens exhibit highly variable physical properties. The elements in the group react with another substance in similar ways. It is the only element to exist at room temperature as a diatomic gas. Gallium (31Ga) is the only metal, except for mercury, caesium, and rubidium, which can be liquid near room temperatures; this makes possible its use in high-temperature thermometers. gas/liquid: red-brown solid: metallic luster. 14. Livermorium is pronounced as liv-er-MORE-ee-em.

All the elements in the oxygen group have six valence electrons, and all are reactive. The elements that is very good in electrical conductivity are gold and copper: elements that is amphoteric are copper, zinc, tin, lead, aluminum and beryllium: elements that is gaseous at room temperature are hydrogen, nitrogen, oxygen, fluorine and chlorine: elements that is solid at room temperature are all metal except mercury and perhaps some unseen radioactive elements. I have 5 neutrons. 10. How many valence electrons are in an atom of each element in Group 13 in the Periodic Table? What's in a name? What are the states of group 7 elements at room temperature?

They are followed by one metalloid and one metal. Mercury is located in Group 12. Tungsten is a greyish-white lustrous metal, which is a solid at room temperature. Naturally occurring barium is a mix of seven stable isotopes. There are 7 diatomic elements, but only 5 diatomic elements at standard temperature and pressure ().The diatomic elements are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. An element is a solid at room temperature but soft enough to be cut with an ordinary knife. Atoms usually react to give an electron arrangement with a full outer shell by losing, gaining or sharing electrons. Group Name: none. 13. Phase at Room Temperature: Expected to be a Solid. Element Classification: Metal. the answer to your other question is: Element 1: Semi-metal (it would be metal but it's not ductile) Element 2: From the info they gave you, you can say it's metal. A diatomic element is a molecule of an element consisting of two atoms. Its atoms have two valence electrons in the 6s sublevel. Tags: Question 16 . All gases are grouped together. 13. Special Notes: Radioactive and Artificially Produced. If you look on a periodic table. Q. CaCO 3---> CaO + CO 2. The name "bromine" is derived from the Greek word for "stench," bromos. It is the only halogen that is not a diatomic molecule and it appears as a black, metallic solid at room temperature. Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength. In group 7’s case this means the halogens will go from gas at room temperature to a solid at room temperature (see 2.9). iii. Radon, helium, xenon, neon, krypton and argon are eight noble gases. There are twenty-two isotopes known, but most of these are highly radioactive and have half-lifes in the several millisecond to several minute range. Astatine is a very rare element, so there is not that much known about this element. Astatine - Astatine is a radioactive element with an atomic number of 85 and symbol At. Wiki User Answered . Its atoms have two valence electrons in the 6s sublevel. an element that is malleable and a good conductor of heat and electricity could have an atomic of: 29. neon and argon are both elements in a group of similar elements, noble gases what properties do these elements have that make them unique . The first three elements in this group are nonmetals. 16. c. above the boiling point, the substance is a gas Matter and Its States . What element is it? Nitrogen is a gas at room temperature. 19. History and Uses: Flerovium was first produced by scientists working … Period Number: 7. Cd, Sb, I. nonmetals in the solid state are poor conductors of heat and tend to. 1 decade ago. Due to relatively weak intermolecular forces, chlorine and fluorine form part of the group known as "elemental gases". It is the only element to exist at room temperature as a diatomic gas. Q. Who am 1? Four students were asked to complete a table for a science assignment. Asked by Wiki User. The halogens exist, at room temperature, in all three states of matter: Solid- Iodine, Astatine. Gas- Fluorine, Chlorine. It is not really a member of any particular group. 3. Hydrogen is unique among the elements because _____. Iodine is a solid that can undergo sublimation in room temperature. Say what? Genrally metals and metaloids (semi-metals, what ever you want to call them) are solid at room temperature. 16. Who am 1? Special Notes: Radioactive and Artificially Produced. What element has the chemical symbol Ir? At room temperature common salt sodium chloride, NaCl, is a solid and methane, CH4, is a gas explain, in terms of the bonds present in each compound, why their physical states is so different.
