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
The oxidation and coordination numbers of cobalt in the compound [Co(NH3)5Cl]Cl2 are, respectively:
oxidation number [ Select ] ["+1", "+2", "+3", "+6"]
coordination number [ Select ] ["6", "8", "5"]
