- [Properties]
-
- Tellurium is usually described as a silvery-white, brittle crystal.
- Tellurium belongs to the carbon group of elements, Group VIA, on the
- periodic table.
- Tellurium is a semimetal, sharing properties with metals and nonmetals.
- (Semimetals are also called metalloids). In its purest state, for example,
- tellurium has a metallic luster; but like a nonmetal, it is easily
- pulverized to a powder.
- Tellurium is not affected by nitric acid, but it combines readily with
- nitric acid to produce tellurous acid. It burns easily in air to produce
- the oxide.
