What will be total spin of Fe3+ ion As its have 3 valence electrons spin shoud - Chemistry - Structure of Atom

Question

What will be total spin of Fe3+ ion? As its have 3 valence
electrons spin shoud be 3 x 1/2 but ans is 5x1/2 how is it possible
please give suitable explanation and common method to find total
spin for ions?

Fe3+
that means atomic no of atom = 26
when we will fill the electrons it will become like
1s(2) 2s(2) 2p(6) 3s(2) 3p(6) 3d(6) 4s(2)
now we know that it is Fe3+ thats y it will loose 3 electrons so
the last valance shell will be 3d(5) as 2 electrons frm 4s and 1
from 3d are removed
and d subshell have 5 orbitals where each orbital should be
singly occupied before getting paired so each 5 electrons in 3d
will b left unpaired therefore they will be having spin of 5 x
1/2
ask if anythng is misunderstood by u or u arre not able to
understand
