Answer» `1s^(2), 2s^(2)2p^(6) , 3S^(1)` `1s^(2) , 2s^(2) 2p^(6) ,3s^(2) 3p^(1)` `1s^(2) , 2s^(2) 2p^(6) , 3s^(2) 3p^(2)` `1s^(2) , 2s^(2) 2p^(6) , 3s^(2)` SOLUTION :Sinceelement (d) hastwo s- electrons in THETHE valenceshelltherefore its `Delta _(i) H_(3)`is muchhighest than its `Delta_(i) H_(2)` sincethe third electronhas tobe lost from the inertgasconfiguration,
