Characteristic

Germanium is a chemical element with symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid. Purified germanium is a semiconductor, with an appearance most similar to elemental silicon.
