Question

The spin-only magnetic moment value of the most basic oxide of vanadium among $V_2O_3, V_2O_4$ and $V_2O_5$ is ______B.M. (Nearest integer)

Answer 1

The most basic oxide among $V_2O_3, V_2O_4$ and $V_2O_5$ is $V_2O_3$
$V_2O_3 = V^{+3}(d^2)$
Magnetic moment
$=\sqrt {(2(2+2))}$
$=\sqrt 8$
$= 2.83$
$≈ 3$

So, the answer is $3$.
