Characteristics:
1.Lustrous, hard, grayish-white solid metalloid in the carbon group, chemically similar to its group neighbors tin and silicon.
2.Purified germanium is a 'p-type' semiconductor material.
3.Conductivity depends largely on added impurities.
4.Attacked by nitric acid and aqua regia, but stable in water, acids, and alkalies in absence of dissolved oxygen, low toxicity.
