Question
The number of d-electrons in Fe2+ (Z = 26) is not equal to the number of electrons in which one of the following?
Options
A.p-electrons in Cl (Z = 17)
B.d-electrons in Fe (Z = 26)
C.p-electrons in Ne (Z = 10)
D.s-electrons in Mg (Z = 12)
Solution
Fe+2 = 3d6 (number of ′d′ electrons = 6) in Cl = 1s2 2s2 2p6 2s2 3p5
total p electrons = 11, which are not equal to number of ′d′ electrons in Fe+2
total p electrons = 11, which are not equal to number of ′d′ electrons in Fe+2
