Mineral Species containing Technetium (Tc)

**Technetium (Tc) Element Properties**
Atomic Mass	98.9062
Atomic Number	43
Name Origins	Greek, Technikos="artificial."
Year Discovered	1937
Discovery Credits	Discoverd by C. Perrier and E. G. Segre at Palermo, Italy.
Remarks	Radioactive metal which does not occur naturally. Silvery as the metal but usually obtained as a gray powder. Resists oxidation, slowly tanishes in moist air, burns in oxygen, dissolves in nitric and sulfuric acids.
