Explain the electronic configuration of cation `Fe^(+)`.

Explanation

Example for electronic configuration of cation.
Electronic configuration of iron Fe (Z = 26) `1s^(2) ,2s^(2), 2p^(6),3s^(2),3p^(6),4s^(2),3d^(6)`
Electronic configuration of `Fe^(+)` (by removing two electrons. `1s^(2) ,2s^(2), 2p^(6),3s^(2),3p^(6),4s^(1),3d^(6)`
