What is the value of 'n' in the 'spin-only' formula for the divalent ion with an atomic number of 25?

Options

  1. A0
  2. B5
  3. C10
  4. D25

Correct answer

B. 5

Step-by-step solution

The 'spin-only' formula μ = √n(n+2) is used with 'n' equal to the number of unpaired electrons, which is 5 in this case.
