An element has d^5 configuration. The total number of electron exchanges possible for it is

Options

  1. A18
  2. B10
  3. C12
  4. D15

Correct answer

B. 10

Step-by-step solution

The total number of electron exchanges possibility is n(n-1) 2 (where, n is the number of shells). By applying this formula for d^5 configuration we get, = 5(5-1) 2 = 5 4 2 = 20 2 =10
