Zinc Facts (Atomic Numberor Zn)

Zinc has the element symbol Zn and atomic number, making it a transition metal and the first element in groupof the periodic table. Sometimes zinc is considered to be a post-transition metal. The element name is believed to come from the German word ‘zinke’, which means "pointed". It appears Paracelsus supplied this name. This is likely a reference to the pointed zinc crystals that ...

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
