For a metal ion, the calculated magnetic moment is 4.90BM4 . 90BM. This metal ion has _______ number of unpaired electrons

Correct answer

0

Step-by-step solution

The magnetic moment of the metal ion can be calculated using

μ=n(n+2)BM\mu = \sqrt{n\left(n + 2\right)}BM

n=n =number of unpaired electrons.

μ=4.90BM\mu = 4 . 90BM

4.90BM=(n)(n+2)BM4 . 90BM = \sqrt{( n ) ( n + 2 )}BM

24=(n)(n+2)24 = ( n ) ( n + 2 )

n=4n = 4
