What is the chemical property of germanium?
Pure germanium is a hard, lustrous, gray-white, brittle metalloid. It has a diamondlike crystalline structure and it is similar in chemical and physical properties to silicon. Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid.
Is germanium Ge a metal?
Germanium falls in the same group as carbon and silicon, but also as tin and lead. Germanium itself is classified as a metalloid. It’s hard at room temperature and looks metallic with a shiny silvery grey finish, but it’s a semiconductor, without some of the key properties of a metal.
What elements does germanium bond with?
Germanium react with O2, forming germanium dioxide, GeO2. At room temperature, the germanium surface is passivated by the GeO2 layer. When heated to red heat, germanium reacts with oxygen in the air, forming germanium dioxide.
What is the chemical bonding and structure of germanium?
Germanium atom forms four covalent bonds with the four neighboring atoms. In covalent bonding each valence electron is shared by two atoms.
What element has the most similar chemical properties to germanium?
silicon
Germanium (Ge), has an atomic number of 32. It is grayish-white, lustrous, hard and has similar chemical properties to tin and silicon.
How is germanium processed?
Like most minor metals, germanium is produced as a by-product of base metal refining and is not mined as a primary material. Regardless of the source of material, all germanium concentrates are first purified using a chlorination and distillation process that produces germanium tetrachloride (GeCl4).
What is the most common isotope of germanium?
Stable 74Ge
Stable 74Ge is the most common isotope, having a natural abundance of approximately 36%. Ge is the least common with a natural abundance of approximately 7%. When bombarded with alpha particles, the isotopes 72Ge and 76Ge will generate stable 75As and 77Se, releasing high energy electrons in the process.
Is germanium a pure substance?
Pure germanium is a hard, lustrous, gray-white, brittle metalloid. It has a diamondlike crystalline structure and it is similar in chemical and physical properties to silicon. Germanium forms many compounds. Therefore it’s a pure substance……..
