Zn (Zinc )
Zinc reacts with both acids and alkalis. It tarnishes in air. It is brittle at normal temperatures but malleable at 100-150°C. It is a fair conductor of electricity, and burns in air at high red heat with the evolution of white clouds of the oxide.

Zinc is used in alloys such as brass, nickel silver and aluminium solder. Large quantities of zinc are used to produce die-castings which are important in the automobile, electrical and hardware industries. It is also used extensively to galvanise other metals such as iron to prevent rusting. Zinc oxide is widely used in the manufacture of very many products such as paints, rubber, cosmetics, pharmaceuticals, plastics, inks, soaps, batteries, textiles and electrical equipment. Zinc sulfide is used in making luminous dials and fluorescent lights.
Zinc, in commerce also spelter, is a metallic chemical element; it has the symbol Zn and atomic number 30. It is the first element of group 12 of the periodic table. Zinc is, in some respects, chemically similar to magnesium, because its ion is of similar size and its only common oxidation state is +2. Zinc is the 24th most abundant element in the Earth's crust and has five stable isotopes.
