Question

Give one similarity and one dissimilarity between primary and secondary valences.

Answer 1

Answer:

Differentiate between primary and secondary valencies? Primary valency is equal to the Oxidation number of central ion. Secondary valency is equal to the coordination number of central metal ion

Answer 2

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.
