Compare the stability of +2 oxidation state for the elements of the first transition series.

Text Solution

Verified by Experts

In general, stability of +2 oxidation state in first transition series decrease from to due to increase in sum of first and second ionisation energies. However .(Mn)^(2+). is more stable dute to half filled .(d)^(circ). - orbitals .(3 (~d)^(5). whereas .(Zn)^(2). is tnore stable due to completely filled d-orbitals .(3 (~d)^(10).
