Question

The number of electrons in d-subshell of
(-34) is equal to
s electrons in Ne
unpaired Ref:28
P-electrons in oxygen
d electrons in
Fe":= 26​

Answer 1

Answer:

The atomic number of Fe is 26 and its electronic configuration is [Ar]4s

2

3d

6

.

Thus, the electronic configuration of Fe

3+

is [Ar]3d

5

.

Hence, it has 5 unpaired electrons in the d subshell.
