- Total L = 2 containing paired electrons for fe2+ 'Co2+ and ni2+ 1) 9 2) 12 3)6 4) 15
Sum of the paired electrons present in the orbital with l=2 in all the species Fe2+, Co2+ and Ni2+ are
Answers (1)
L = 2 means d orbitals
electronic configuration of Fe2+ = [Ar] 3d6
six electrons in d orbitals 4 will be unpaired 2 will be paired
electronic configuration of Co2+ = [Ar] 3d7
three electrons will be unpaired four will be paired
electronic configuration of Ni2+ = [Ar] 3d8
two electrons will be unpaired and six will be paired
So the sum of paired electrons is 2+4+6=12.
