Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a blue-silvery appearance when oxidation is removed. It is the first element in group 12 of the periodic table.
Zinc is found in several ores, the principal ones being zinc blende (zinc sulfide) and calamine (zinc silicate). The principal mining areas are in China, Australia and Peru. Commercially, zinc is obtained from its ores by concentrating and roasting the ore, then reducing it to zinc by heating with carbon or by electrolysis.
Physical Properties: Zinc is a bluish-white, lustrous metal. It is brittle at ambient temperatures but is malleable at 100 to 150°C. It is a reasonable conductor of electricity. The density of zinc is 7.140 g/mL, which means the metal will sink in water and is relatively heavy. Chemical Properties:
The International Zinc Association explains that zinc is critical to proper cellular growth and mitosis, fertility, immune system function, taste and smell, healthy skin and vision. United States pennies are constructed with a zinc core comprising 98% of their weight. The remaining 2% is an electrolytically plated copper coating.
Please note that g/cm3 can also be written as gcm-3 When lb (pounds) is used in this table, this is actually pounds mass, equivalent to approximately 0.454 kg.

Zinc also reacts with other substances: halogens, oxygen, chalcogens, alkalis, acids, ammonium and ammonia salts, and also with weaker metals. Zinc does not react with nitrogen, and is an amorphic metal. In reactions with alkalis, the element forms complex compounds – hydroxo-zincates.
