Features
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.
