Tellurium
Tellurium
Physical Properties
Atomic number: 52
Atomic Weight: 127.60
Melting Point: 449.8°C
Boiling point: 1390°C
Density: 6.24 g/cm3
Grey powder or silver white metallic luster crystal.
Chemical property
It will generate two tellurium oxide when burning in the air or oxygen and it can not react with water or non-oxidative acid. Tellurium with the halogens react violently and produce the tellurium halide. Besides, it can not react with the hvdrogen in high temperature
