Cobalt

When someone talks about the colour of cobalt, they assume blue. In fact, there are four dihalides of cobalt (II) that are known to exist; cobalt(II) fluoride (CoF2, pink), cobalt(II) chloride (CoCl2, blue), cobalt(II) bromide (CoBr2, green), cobalt(II) iodide (CoI2, blue-black).

Cobalt & It's Traits

Cobalt, like nickel, is found only in the earth's crust in chemically combined form. It's melting point is 1495 °C,it's atomic number is 27, it's atomic mass is 58.933195 ± 0.000005 u, the symbol is Co, and the descoverer is Georg Brandt.

Cobalt is a huge substance that is used in society today. It's primarily used as the metal, in preperation of magnetic, wear-resistant high strength alloys. The compounds in cobalt - cobalt silicate and cobalt(II) aluminate - have a distinctive blue colour to the element. Cobalt only occurs naturally in one state - cobalt-59.
