Question

Predict the magnetic moment and
the number of unpaired electrons in
[Fe(H20)6]3+. Atomic number of Fe is
26.​

Answer 1

Answer: 1.732

Explanation: As the formula for calculating magnetic moment is $\sqrt{n(n+2)}$ where n is the number of unpaired electron in the element or ion considered .

Thereby considering the electronic configuration of Fe+3 ion , it has got 1 unpaired electron . Thus by putting the value of n=1 in the equation mentioned above the answer comes out to be $\sqrt{3}$ that is 1.732
