A transition elements with atomic number 24 will have its magnetic moment

Options

  1. A5.92 BM
  2. B6.93 BM
  3. Cit will be diamagnetic
  4. Dit will be more than 8 BM

Correct answer

B. 6.93 BM

Step-by-step solution

Outer electronic configuration of the element with atomic number 24 is 3 d⁵ 4 s¹ . Number of unpaired electrons =6 aligned &= n(n+2) BM = 6(6+2) = 48 &=6.928=6.93 BM aligned
