Question

The outer electronic configuration of the ground state chromium atom is `3d^(2),4s^(2)`

Answer 1

`Cr(Z = 24)`
`[Ar]3d^(6)4s^(1)`
This is because `d^(5)` is a more half -filled configuration Reason for the stablity of half-filled and fallty filled ortained are symmetry and excharge energy
