Description of the substance

The name "Thallium" comes from the greek word thallos, which means a joung green branch. Thallium was sprectroscopically discovered; because of the green spectral line it got his name. Thallium was isolated in 1862 by Crookes and about at the same time by Lamy.
Thallium is a soft metal; it can be cut with a knife. When freshly exposed to air, thallium exhibits a metallic luster, but soon develops a bluish-gray tinge, resembling lead in appearance. A heavy oxide builds up on thallium if left in air, and in the presence of water the hydride is formed.
The element and its compounds are toxic and should be handled carefully. Contact of the metal with skin is dangerous. Thallium is suspected of carcinogenic potential for man.
