Question

which ion has the stable electronic configuration Ni2+ or Fe3+

Answer 1

Answer:

Answer. The electronic configuration pf Fe+3 = [Ar] 3d5. So, as we know that half filled subshells are more stable, Thus we can see that Fe+3 ion will be more stable than Ni+2 , because of more number of exchanges in Half filled subshell.

Answer 2

Here we have to find out the stable electronic configuration among  Ni²⁺ and Fe³⁺.

First, we will write the electronic configuration of Ni²⁺ and Fe³⁺.

• Electronic configuration of Ni²⁺: 1s²2s²2p⁶4s²3d⁸

• Electronic configuration of Fe³⁺: 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵

Now, we know that fully filled orbitals and half-filled orbitals are exceptionally stable.

In, Fe³⁺ the orbital is half-filled.

So, the electronic configuration of Fe³⁺ will be more stable.
