This picture shows zinc as a solid at room temperature

On the Pauling Scale, zinc has a electronegativity of 1.65. Electronegativity is the power of an atom while it is in a molecule to attract electron density to itself.

Common Uses

Period Table

The most common ion of zinc is the +2 charge. Its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2. The short hand version is [Ar] 3d10 4s2. Zinc's period number is 4 and is located in Group 12. It is also a transitional metal. Zinc has 30 protons, 30 electrons and 35 neutrons

Physical Properties of Zinc

Zinc can be mined, the most common ore is sphalerite which is a form of zinc sulfide. At room temperature, zinc is a solid metal with a sliver-grey color. Zinc is not malleable or ductile at room temperature. Zinc's melting point is 419.5°C (787.1°F) and its boiling point is 908°C (1,670°F). Its density is 7.14 grams per cubic centimeter. Zinc is a fairly soft metal, its hardness is 2.5 on the Mohs scale.

Zinc is often used to galvanize other metals, this prevents rusting. Zinc is used in alloys such as bronze and brass. These alloys are used in building other things such as cars, gutters, and building materials.

The name zinc originates from the German word 'zin', meaning tin. It was discovered by Andreas Marggraf. Zinc was first recognized as an element in 1749 but was already being used by the Greeks and the Romans before 20 B.C.
