Answer» SOLUTION : Thisruledealwith thefillingof electronsintothe orbitalbelongingto thesamesubshell . Rule :Pairingof ELECTRONIN theorbitalsnot takepalceuntileachorbitalbelongingto thatoccupied. Insubshelllfirstoneelectronarrangeand thanafter pairingwill takepalce. Thereare THREE p fived andsevenf orbitalsthereforethe pairingof electronswill startin the p , da and f orbitalswith theentryof `4^(th), 6^(th)`and `8^(th)`electronrespectively. Example: N (Z =7)in `1s^(2) 2s^(2)2p_(x)^(1) 2p_(x)^(1)2p_(z)^(1)` and ` O (z = 8)` in`1s^(2)2s^(2) 2p_(x)^(2)2p_(y)^(1)2p_(z)^(1)` typeelectronconfigurationoccurs. |
