Thallium (Tl ) by %

**Thallium (Tl) Element Properties**
Atomic Mass	204.3833
Atomic Number	81
Name Origins	Greek, thallos = "green twig."
Year Discovered	1861
Discovery Credits	Discovered by W. Crookes at London, UK; isolated in 1862 by C. A. Lamy at Paris, France.
Remarks	Soft, silvery-gray metal. Tarnishes readily in moist air and with steam reacts to form TlOH. Attacked by acids, rapidly by HNO₃. Little used because of its toxicity, but still employed in special glasses. Diagnostic tests: Thallium and its salts are quite volatile when heated with the blowpipe and impart an intense green color to the flame test.
