Question

Correct set of quantum numbers representing the
last electron of iron (Fe) will be
(1) n = 4, l = 0, m = 0, s = +1/2
(2) n = 3, l = 2 m = +2,= +1/2
(3) n = 3, l= 1, m = 0, S = +1/2
(4) n = 3, l= 1. m = -2, s = 0​

Answer 1

Answer:

here is ur answer

Explanation:

1s2 2s2 2p6 3s1

Answer 2

Answer:

1s² 2s² 2p^6 3s² 3p^6 4s² 3d^6

so last electron will be in 3d^6

there fore option 2 is correct
