Thallium

Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray posttransition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to William Crookes and ClaudeAuguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production. . Both used the newly developed method of flame ......
