I think option C is right.
Since outer most electron that is in the d orbital there number are 10 and also Fe2+ (Z=26) that's outer most electron numbers are 10 in d orbital.

Answer must be option C) Fe (26).

I think the answer is B because, when its Mg=12, it is 1s2 2s2 2p6 3S2 but the Fe=26 is 1s2 2s2 2p6 3s2 3p6 4s2 3D6.
Even after you lose one electron from the 'd' of Fe orbital it still is not equal to that of Mg.

I think the answer is correct because after D, orbital looses their one electron it stabilised fully.

Actually half filled and full filled orbital are much more stable than partially filled orbital, that is why fe will first loose one electron from d orbital to half filled the 3d orbital then loose one other electron from 4s orbital and become more stable.

1s2 2s2 2p6 3s2 3p6 4s2 3d6 is Fe electronic configuration.
While Cl is having 1s2 2s2 2p6 3s2 3p5, so Fe2+ is having configuration as below 1s2 2s2 2p6 3s2 3p6 4s0 3d6.
While Cl is having 1s2 2s2 2p6 3s2 3p5, so Fe2+ is having configuration as below 1s2 2s2 2p6 3s2 3p6 4s0 3d6.

Neon is a gas (group 8), Valence electron - 2. Mg and Friday are electro positive metals +2. Click is not equal because it has - 1(2, 8 7). The answer is done.

Number of d-electrons in Fe2+ and number of p-orbitals in Cl are same...

After seeing explains, I don't think any other explanation is required.

Thanks for answers. The number of d-electron in fe2+ is not equal to that of p-electron in cl.
