Answer:
Primary valence and secondary valence
primary valencies are variable while secondary valencies are stable. The primary valences are ionisable, and are satisfied by negative ions. The secondary valences are non-ionisable, and are satisfied by negative ions or neutral molecules. The secondary valence is equal to the coordination number of a metal, and remains fixed for a metal.

Answer:
The primary valence is the number of negative ions needed to satisfy the charge on the metal ion. ... The secondary valence is the number of ions of molecules that are coordinated to the metal ion. Werner assumed that the secondary valence of the transition metal in these cobalt(III) complexes is six.
