In the following species, how many species have same magnetic moment? (i) Cr ²⁺ (ii) Mn ³⁺ (iii) Ni ³⁺ (iv) Sc ²⁺ (v) Zn ²⁺ (vi) V ³⁺ (vii) Ti ⁺

Options

  1. A1
  2. B3
  3. C2
  4. D4

Correct answer

C. 2

Step-by-step solution

Among the given species, Cr ²⁺ and Mn ³⁺ have same number of unpaired electrons. aligned & Unpaired electrons, n=4 & Magnetic moment, aligned & = n(n+2) = 4(4+2) & = 24 BM aligned aligned
