Zinc(Zn) atomic and molecular weight, atomic number and elemental symbolZinc is a Block D, Group 12, Period 4 element. The number of electrons in each of zinc's shells is 2, 8, 18, 2, and its electron configuration is [Ar] 3d10 4s2. The zinc atom has a radius of 133.5.pm and its Van der Waals radius is 139.pm. In its elemental form, CAS 7440-66-6, zinc has a silver-gray appearance. Zinc Bohr ModelIt is brittle at ordinary temperatures but malleable at 100 °C to 150 °C. Elemental ZincIt is a fair conductor of electricity, and burns in air at high red producing white clouds of the oxide. Zinc is mined from sulfidic ore deposits. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. It is is the 24th most abundant element in the earth's crust and the fourth most common metal in use (after iron, aluminum, and copper). Zinc was first isolated by Andreas Marggraf in 1746. The element name zinc originates from the German word "zin" meaning tin. See Zinc research below.

Zinc has unusual electrical, thermal, optical, and solid-state properties that have not been fully investigated. The metal is employed to form numerous alloys with other metals. Brass, Nickel, Silver, commercial Bronze, soft solder, and Aluminum solder are some of the more important alloys. Zinc is used to produce die castings which are used extensively by the automotive, electrical, and hardware industries. Zinc is also used to galvanize other metals such as iron to prevent corrosion. High Purity (99.999%) Zinc Oxide (ZnO) PowderZinc oxide is widely used in the manufacture of paints, rubber products, cosmetics, pharmaceuticals, floor coverings, plastics, printing inks, soap, storage batteries, textiles, and electrical equipment. Zinc sulfide is used in making luminous dials, X-ray and TV screens, and fluorescent lights. High Purity (99.9999%) Zinc (Zn) Sputtering TargetThe chloride and chromate are also important compounds. Zinc is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity). Elemental or metallic forms include pellets, rod, wire and granules for evaporation source material purposes. Zinc nanoparticles and nanopowders provide ultra-high surface area which nanotechnology research and recent experiments demonstrate function to create new and unique properties and benefits. Oxides are available in powder and dense pellet form for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Zinc is also available in soluble forms including chlorides, nitrates and acetates. These compounds can be manufactured as solutions at specified stoichiometries.

Zinc is considered non-toxic in healthy doses but can cause nausea if taken in excess. Safety data for Zinc and its compounds can vary widely depending on the form. For potential hazard information, toxicity, and road, sea and air transportation limitations, such as DOT Hazard Class, DOT Number, EU Number, NFPA Health rating and RTECS Class, please see the specific material or compound referenced in the Products tab below.
