Because of its low atomic number and very low absorption for X-rays, it is used as radiation windows for X-ray tubes and X-ray detectors. ELECTRICAL CONDUCTIVITY Due to the presence of loosely held valence electrons which are free to move throughout the metal structure, the alkali metals … alkaline earth metal Bedeutung, Definition alkaline earth metal: 1. any of the chemical elements beryllium, magnesium, calcium, … Title: Alkaline Earth Metals 1 Alkaline Earth Metals. Alkali metals are so-called because when they react with water, they create highly alkaline substances. ... Francium is the rarest of the alkali metals and the second rarest element in the Earth's crust (only 340-550 grams or about 1 pound is estimated to be in the Earth's crust). While most metals form arsenides, only the alkali and alkaline earth metals form mostly ionic arsenides. Later, it was discovered that the elements being classified as alkaline earth metals were actually oxides of those metals — the metal atoms were combining with oxygen. M + H 2 O H 2 + M(OH) 2 (all alkali metals can reduce water to produce hydrogen gas, except Be) Note – Be has least reducing nature among alkaline earth metals. While metals of the p, d and f block of the periodic table have all been shown to engage in π systems, there has never before been any aromatic or antiaromatic compounds containing s-block elements. The alkali metals and the alkaline earth metals all form saline hydrides. Uses of alkali metals: i. Lithium metal is used to make useful alloys. Uses of alkali metals. This layer, which acts as an interphase between the metal and the solution, has the properties of a solid electrolyte. Ca is used in the extraction of metals from their oxide.
