How many "d" electrons are present in Cr^+2 ion
Answered by admin @
ATOMIC NUMBER OF CR OR CROMIUM = 24
NO OF ELECTRONS=24
A POSITIVE SIGN INDICATES THAT IT LOST 1 ELECTRON AND 2 MEANS IT HAS LOST TWO ELECTRONS
NOW ELECTRONIC CONFRIGURATION OF CR=[AR]4s^2 3d^4
NOW ELECTRONIC CONFRIGURATION OF CR^2=[AR]3d^4
AS CHROMIMUM WILL LOOSE ELECTRON FROM ORBITAL
THEREFORE CR^2 HAS 4 D ORIBITALS
HENCE OPTION A IS CORRECT
HOPE THAT THIS WILL HELP YOU OUT AND BEST OF LUCK FOR YOUR FUTURE AND JEE✔✔
