Zinc

Zinc is a chemical element of a secondary subgroup of the second group, the fourth period of the periodic system of D.I. Mendeleev, with atomic number 30. It is denoted by the symbol Zn (lat. Zinc).

A simple substance is zinc under normal conditions – a brittle bluish-white transition metal (tarnishes in air, being covered with a thin layer of zinc oxide).

Zinc alloy with copper – brass – was already known in Ancient Greece, Ancient Egypt, India (VII century), China (XI century).

Zinc is the fourth most used metal in the world after iron, aluminum and copper, and the third among non-ferrous metals.
