HISTORY,
BACKGROUND & USES:
Discovered in 1782 by Franz Joseph Müller von Reichenstein. Tellurium is a semi-metallic element that resembles both physically
and chemically to selenium (34). Tellurium exists in two forms:
a silvery-white, brittle, crystalline solid that has a metallic
lustre and a amorphous powder that is dark grey to brown. It burns
in air and oxygen with a blue-green flame.
