Step-by-step solution

Fe→[Ar]4s23d6Fe \to [ Ar ] 4{s}^{2}3{d}^{6} In the ground state of atomic Fe ( Z = 26 ) , the spin-only magnetic moment is × 10 ^ - 1 BM . (Round off to the

Number of unpaired e−=4{e}^{-} = 4

μ=4(4+2)B.M.\mu = \sqrt{4 ( 4 + 2 )}B . M .

μ=24B.M\mu = \sqrt{24}B . M

μ=4.89B.M\mu = 4 . 89B . M

μ=48.9×10−1B.M\mu = 48 . 9 \times {10}^{- 1}B . M

Nearest integer value will be 49.49 .
