What may be the stable oxidation state of the transition element with the following d electron configurations in the ground state of their atoms: 3d3, 3d5, 3d8 and 3d4? 

The stable oxidation state of transition element with the d electron configuration in ground state of atoms are as follows:

S. No. d-electron

configuration

Symbol of element

Stable oxidation states

1.

2.

3.

4.

3d3

3d4

3d5

3d8

Vanadium[V](4s23d3)

Chromium Cr(4s23d4)

Manganes Mn(4s23d5)

Nickel Ni(4s23d8)

+2, +3, +5

+2, +3, +6

+2,+7

+2,+4

It should be noted that lower stable oxidation state generally leads to ionic bond and higher oxidation state corresponds to covalent bond.
