Give the electronic confiuration of Mn^(2+) and Cr^(3+). |
|
Answer» SOLUTION :`Mn (Z = 25)` `Mg rarr Mn^(2+) + 2e^(-)` `Mn^(2+)` Electronic configuration is `1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^5` `Cr (Z = 24)` `Cr rarr Cr^(3+) + 3E^(-)` `Cr^(3+)` Electronic configuration is `1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^3`. |
