Give the electronic configuration of Mn^(2+) and Cr^(3+)

1.	Give the electronic configuration of Mn^(2+) and Cr^(3+)
Answer» Solution :MN(Z=25) `MnrarrMn^(2+)+2E^(-)` `Mn^(2+)` electronic cinfiguration is `1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(5)` Cr(Z=24) `CrrarrCr^(3+)+3e^(-) ` `Cr^(3+)` electronic CONFIGURATION is`1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(3)`
