Electron configuration of Cobalt is [Ar] 3d7 4s2
The symbol of this chemical element is Co and 27 is its atomic number.
Cobalt can be mined only in chemically combined form and the free element – a silver-grey metal, is obtained by smelting.
Today it is produced more as a by-product of copper and nickel mining. The Democratic Republic of Congo, Central African Republic and Zambia produce most of the available Cobalt in the world.
