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)
Correct Answer: 3
Solution and Explanation
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 \(3\).

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
