Question: A compound of a metal ion $ {{M}^{x+}}(Z=24) $ has a spin only magnetic moment of $ \sqrt{15} $ Bohr Magnetons. The number of unpaired electrons in the compound are
Options:
A) 2
B) 4
C) 5
D) 3
Show Answer
Answer:
Correct Answer: D
Solution:
Magnetic moment $ \mu =\sqrt{n(n+2)} $ where n = number of unpaired electrons
$ \sqrt{15}=\sqrt{n(n+2)}\therefore n=3 $
