How many unpaired electorns are present in the ground state of(i)Cr^(2+)(Z=24)(ii)Ne(Z=10) |
|
Answer» Solution :(i)`Cr(Z=24)``1S^(2)2s^(2)2p^()3s^(2)3p^(6)3d^(5)4s^(1)` `Cr^(3+)-1s^(2)2s^(2)2p^()3s^(2)3p^(6)3d^(4)` It CONTAINS 4 UNPAIRED electrons. (ii)Ne(Z=10)`1s^(2)2s^(2)2p^(6)`.No unpaired electrons in it. |
