COBALT

Cobalt was discovered by Georg Brandt. Cobalt is in the transition metal group. Its atomic number is 27. Its symbol is Co. Its atomic mass is g/mol.

 Its colour is metallic gray.  Its boiling point is 2927 celcius degree  Its melting point is 1495 celcius degree

 It joins with nikel and iron and then they product “Alnico”  Alcino is an Alloy

 Cobalt uses in glasses industry and ceramic industry.  Cobalt is resistant,so it uses in electrolysis plating.
