Assumptions of Werner’s Theory

The important postulates of Werner’s theory are:

The central metal or the metal atoms in coordination compounds show two types of valency. They are the primary and secondary valency.

The primary valency relates to the oxidation state and the secondary valency relates to the coordinate number.

The number of secondary valences is fixed for every metal atom. It means that the coordination number is fixed.

The metal atom works towards satisfying both its primary and secondary valencies. A negative ion satisfies the primary valency. On the other hand, a negative ion or neutral molecules satisfy secondary valencies.
