The number of d-electrons retained in Fe^(2+) (At. no. of Fe= 26) ion – InterviewSolution

1.	The number of d-electrons retained in Fe^(2+) (At. no. of Fe= 26) ion is
Answer» 4 5 6 3 Solution :ELECTRONIC configuration of `""^(26)Fe=[AR]^(18)3D^(6)4s^(2)` Electronic configuration of `Fe^(2+)=[Ar]^(18)3d^(6)` `therefore` No. of d-electrons = 6.
