Question

plz Give the definitions of primary valence and
secondary valance of metals?

Chandra Prakash · Accepted Answer

Primary
Valency

Secondary
Valency

Primary valency may
be defined as +ve charge raised over central metal ion as its
oxidation state

Secondary valency
may be defined as no of mono dentate or equivalent to mondentate
ligand attached to central metal ion It defines the Coordination
No

It is ionisable and
variable

It is non ionisable
and fixed

Example: [Cr(H2O)6]Cl3 = Primary
valency is Chloride ion

Secondary valency
is H2O molecules

Primary Valency	Secondary Valency
Primary valency may be defined as +ve charge raised over central metal ion as its oxidation state	Secondary valency may be defined as no of mono dentate or equivalent to mondentate ligand attached to central metal ion. It defines the Coordination No.
It is ionisable and variable	It is non ionisable and fixed
