Question

in complex, the primary valency of the metal is always ionic?

​

Answer 1

Answer:

Primary valency is basically the oxidation state of the metal ion forming the complex and most metals basically have a positive charge, so it has to balanced by anions.

Answer 2

In complex, the primary valence of the metal is always ionic:

• A metal loses electrons and becomes positively charged, which can only be neutralised by interacting with negatively charged ions.

• The amount of negative ions required to fulfil the charge on the central metal ion in a coordination complex is known as its primary valency.

• The negatively charged ions always satisfy the primary valency, which corresponds to the oxidation state of the metal ion.

• The coordination number of the metal complex is represented by secondary valency.
