Germanium Statistics and Information

Germanium is mainly a byproduct of zinc ore processing. It is a hard, grayish-white element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass. In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator. The development of the germanium

Germanium the essentials

Germanium is available through the treatment of germanium dioxide, GeO 2, with carbon or hydrogen. The extraction of germanium from flue dust is complex because of the difficulty in separating it from zinc, which is also present. GeO 2 + 2C → Ge + 2CO. GeO 2 + 2H 2 → Ge + 2H 2 O. Very pure germanium can be made by the reaction of GeCl 4

What is the electron configuration for Zn2+?

Jun 30, 2016The atomic number of zinc is 30, which means that all zinc atoms have 30 protons in their nuclei. A neutral atom has equal numbers of protons and electrons, so a neutral atom of zinc would have 30 electrons. The electron configuration of a neutral zinc atom is #1s^22s^22p^63s^23p^63d^104s^2#.. The #Zn^(2+)# ion has lost two electrons, which
