Number of electrons with magnetic quantum number equal to zero present in the outer most orbit of `Co^(2+)` are..........

Text Solution

Verified by Experts

The correct Answer is:
6
Configuration of `Co^(2+)` is `1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(9)`
For 3s electrons, m = 0
For 3p electrons, `m = -1, 0, -1`
For 3d electron `m = -2, -1, 0, +1` and `+2+2+2 = 6`
