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. The coating prevents the object treated from rusting. Say 'oxygen' or 'iodine' and there is no clue in the sound of the word to the nature of the element.

We're rarely aware of it, unlike its flashier neighbours in the period table, but zinc is a workhorse element that helps us all. Au… Where more than one isotope exists, the value given is the abundance weighted average. Zinc oxide is widely used in the manufacture of very many products such as paints, rubber, cosmetics, pharmaceuticals, plastics, inks, soaps, batteries, textiles and electrical equipment. Naturally occurring zinc (30 Zn) is composed of the 5 stable isotopes 64 Zn, 66 Zn, 67 Zn, 68 Zn, and 70 Zn with 64 Zn being the most abundant (48.6% natural abundance).Twenty-five radioisotopes have been characterised with the most abundant and stable being 65 Zn with a half-life of 244.26 days, and 72 Zn with a half-life of 46.5 hours. It is given by the ratio of the shear stress to the shear strain. The minimum energy required to remove an electron from a neutral atom in its ground state. Zinc In 1961, the Commission recommended Ar (Zn) = 65.37 based on the chemical determinations. Some galvanization is more literally electrical - car bodies, for example, are electroplated with zinc to apply a thin, even layer. It has a half life of around 4.3×10 18 year, which is so high that it is considered almost stable.
