Zinc is a metallic chemical element with symbol Zn and atomic number 30. It is part of group 12 (or IIB) of transitional elements on the periodic table of elements. It is found in the earth and several minerals, including sphalerite, contain zinc.

Zinc is a dark brown-grey metal with a relatively low density (7.14 g/cm3). It is a ductile and malleable metal, which means it can be easily bent or shaped. It is also relatively soft at room temperature, but hardens as it cools. It is very resistant to corrosion and oxidation.

Zinc is very commonly used in alloys including copper (the most commonly used common alloy, copper-zinc, is commonly referred to as brass), aluminum, and brass. It is also used in the manufacture of coatings and other galvanized items. It is also added to several metals to improve their corrosive properties. In addition, zinc is used in the mechanical and electrical industry to produce various parts and components.

Zinc is also very important for human health, as it is an essential micronutrient. The majority of zinc in the bloodstream is found in organs and tissues, including the skin, liver, and kidneys. Zinc plays an important role in protein and lipid metabolism, and helps maintain immune health and reproduction.
