Zinc is a chemical element with the symbol Zn and atomic number 30, classified as a transition metal that appears as a bluish-white, lustrous solid at room temperature. It is the 24th most abundant element in Earth’s crust and occurs naturally in ores such as sphalerite (zinc sulfide), from which it is extracted for industrial use.

Essential for human health, zinc functions as a cofactor in over 300 enzymes, supporting immune function, wound healing, DNA synthesis, and growth.
Physically, zinc has a density of 7.134 g/cm³, melts at 419.53°C, and boils at 907°C, making it malleable at temperatures between 100°C and 150°C despite being brittle at ordinary conditions.

Chemically, it exhibits a primary oxidation state of +2 and is amphoteric, reacting with both acids and bases to form compounds like zinc oxide (ZnO) and zinc chloride (ZnCl). These properties enable its role as a fair electrical conductor and its use in preventing corrosion through galvanization, where it coats iron and steel to protect against rust.

Industrially, zinc ranks as the fourth most widely used metal after iron, aluminum, and copper, with about 75% of production consumed as metallic zinc for applications including brass and bronze alloys, die castings in automotive parts, and battery electrodes.

The remaining 25% goes into compounds, such as zinc oxide for rubber vulcanization, paints, cosmetics, and fertilizers. Global mine production reached approximately 12 million metric tons of zinc content in 2024 (estimated), primarily from countries like China, Peru, and Australia.

Biologically, zinc is an essential micronutrient required in small amounts—recommended daily allowances are 11 mg for adult men and 8 mg for adult women—with deficiency linked to impaired growth, increased infection risk, and delayed wound healing, particularly in developing regions.

It is naturally present in foods like oysters, nuts, beef, and fortified cereals, and supplementation can reduce the duration of common colds by up to two days and lower pneumonia incidence in children by 10-20%. While non-toxic in typical dietary levels, excessive inhalation of zinc oxide dust can cause respiratory irritation known as “metal fume fever.”
