Mostly, it is present in the form of ores and minerals of copper and lead. Allotropes Initially the zinc simply stops the air getting to the iron, but later the zinc corrodes in preference to iron in an electro-chemical process, acting as a so-called sacrificial anode. 2. Zinc can be carcinogenic in excess. The temperature at which the solid–liquid phase change occurs. Values are given for typical oxidation number and coordination. We're rarely aware of it, unlike its flashier neighbours in the period table, but zinc is a workhorse element that helps us all. It is given by the ratio of the shear stress to the shear strain. There are five stable isotopes of zinc, these include zinc-64, zinc-66, zinc-67, zinc68 and zinc-70.

With zinc also appearing in anti-dandruff shampoos in the form of zinc pyrithione and in underarm deodorants as zinc chloride, this is an element that even makes us more attractive to the opposite sex. Some elements exist in several different structural forms, called allotropes. The unit of measure for mass is the atomic mass unit (amu). Values are given for typical oxidation number and coordination. All Rights Reserved. The name is derived from the German, 'zinc', which may in turn be derived from the Persian word 'sing', meaning stone. The substance was known before - objects with zinc in them date back over 2,500 years, and the Romans used that gold coloured alloy - but zinc wasn't identified as a distinct material in the west until the seventeenth century. Isotopes It stops iron rusting, soothes sunburn, keeps dandruff at bay, combines with copper to make a very familiar gold-coloured alloy and keeps us alive, but we hardly notice it. These values were determined using several different methods. Images © Murray Robertson 1999-2011 But zinc is different. Zinc is a chemical element with symbol Zn and atomic number 30.
