Question

explain oxidation states of first row elements of transition series​

Answer 1

answer-

The variability of oxidation state of transition metal is due to the involvement of nd and ns electron. Since, the energy b/w these orbitals is not high so electron can be lost from d-orbital as well. The variability of oxidation state arises due to the incomplete filling of d-orbitals such that their O.S differ each other by unity.

Answer 2

Answer:

the variability of oxidation state of transition metal is due to the involvement of ND and NS elections since,the energy B/W these orbital is not high so election can be lost from d-orbital as well
