Solution
The correct option is C negative ions The primary or principal valency; this is the ionisable valency.
A metal always gives electron and becomes positively charged that can be neutralized by bonding with negative ion only. In a coordination compound, the number of negative ions needed to satisfy the charge on the central metal ion is it's primary valency.
