The spin-only magnetic moment value of the most basic oxide of vanadium among V 2 O 3 ' V 2 O 4 and V 2 O 5 is____B.M. (Nearest integer)

Step-by-step solution

V 2 O 3 is the most basic oxide among the given oxides. In V 2 O 3 , Vanadium is in + 3 oxidation state V 3 + ⇒ Ar 3 d 2 4 s 0 So, 2 unpaired electrons are there, Its magnetic moment is equal to μ = n n + 2   BM = 2 2 + 2   BM = 2 . 83   BM   ≃   3   B M ( n = number of unpaired electrons)
