1.	The configuration [Ar]3d^(5)4s^(1) in the first excited states exists for
Answer» `FE^(2+)` `CO^(3+)` `Mn^(+)` `Cr` SOLUTION :`Fe^(2+)` : Ground state = `3d^6` `""` EXCITED state `= 3d^5 4s^1` b) `Co^(3+)`: Ground state = `3d^6` `""` Excited state `=3d^5 4s^1` c) `Mn^(+) : ` Ground state =`3d^5` `""` Excited state `= 3d^5 4s^1` d) Cr :Ground state `=3d^5 4s^1` `""`Excited state :Excited state `=3d^5 4p^1`
