We’re being asked to determine the oxidation and coordination number of Co in [Co(NH3)5Cl]Cl2.


• Oxidation Number: number of electrons lost by an atom

• Coordination Number: number of ligands attached to a central metal ion


For oxidation number:

x + 2(–1) = 0, where x = charge of [Co(NH3)5Cl]

x – 2 = 0

x = +2
