Also known as Zn, element 30, 30Zn, Zn(ii), Zn2+

Zinc is a chemical element; it has symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny blue whitish appearance when surface oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. Zinc is the 24th most abundant element in Earth's crust, with an average concentration of 70 grams per ton. Zinc also has five stable isotopes; the most abundant of which, Zn-64, comprises nearly half of zinc's total abundance. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (

OverviewAI-generated

Zinc is a chemical element with the symbol Zn and atomic number 30. Its standard atomic weight is 65.38, while PubChem lists the weight as 65.4. The element has an electronegativity of 1.65 and a common oxidation state of 2. Its ionic radius is 0.90.

Physically, zinc melts at 419 degrees and boils at 907 degrees. The minimal lethal concentration is recorded as 450. In chemical notation, the canonical SMILES string is "[Zn]" and the Unicode character is "鋅". It has zero hydrogen bond donors and acceptors, with a topological polar surface area of 0.
