Cobalt is found in group 9 of the Periodic Table of Elements.

Also Cobalt is found in earths crust.(The outer layer of earth)


There are many compounds and mixtures involved with Cobalt.

  • Cobalt difluoride: CoF2
  • Cobalt sulphide: CoS
  • Cobalt persulphide: CoS2
  • Dicobalt trisulphide: Co2S3
  • Cobalt trifluoride: CoF3
  • Cobalt tetrafluoride: CoF4
  • Cobalt diiodide: CoI2
  • Cobalt oxide: CoO
  • Dicobalt trioxide: Co2O3
  • Tricobalt tetraoxide: Co3O4
  • Cobalt is also looks a lot like iron, nickel, and other metals.
  • A chemical reaction with Cobalt is when you put in acid. When you do this the Cobalt dissolves slowly.

    Is it dangerous?

    Cobalt can be dangerous when you breath in a lot of it. You can get lung cancer because Cobalt is toxic.
