Question

The number of d-electrons retained in Fe²⁺ (At. no. of Fe = 26) ion is(a) 4 (b) 5(c) 6 (d) 3

Answer 1

Fe2+ means 2 electron are removed from 4s orbital ( less energy from 3d) 1.

So in 3d subshell

6 electrons are present in which 3 electrons are unpaired.

I think d option is correct

Hope this helps you ......
