Question

A compound of vanadium has a magnetic moment μ of 1.73 BM. If the vanadium ion in the compound is present as $V^{x+}$, then the value of x is?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is D 4

$Magneticmoment=\sqrt{n(n+2)}=1.73$
$n=1$
$V=\left[Ar\right]3d^{3}4s^2$
$V^{4+}=\left[Ar\right]3d^1$
