Thallium - Wikipedia

Thallium is a chemical element with the syol Tl and atomic nuer 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium reseles tin, but discolors when exposed to air.Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production.


9/6/2016· Simple metal/metalloid oxides have only one type of metal/metalloid ion, which bonds to an oxide ion (O 2−) in proportion to balance the charges on the metal/metalloid ion. For example, the magnesium ion Mg 2+ , the aluminium ion Al 3+ and the silicon ion Si 4+ coine with the Oxide ion O 2− ion to form MgO (Periclase), Al 2 O 3 (Corundum) and SiO 2 (Silica).


The calcium atom has a radius of 197 pm and a Van der Waals radius of 231 pm. Calcium was discovered and first isolated by Sir Humphrey Davy in 1808. It is the fifth most abundant element in the earth''s crust and can be found in minerals such as dolomite, gypsum, plagioclases, amphiboles, pyroxenes and garnets.
