Which of the following ions has the highest magnetic moment

Options

  1. AT i 3 +
  2. BS c 3 +
  3. CM n 2 +
  4. DZ n 2 +

Correct answer

C. M n 2 +

Step-by-step solution

T i 3 + → 3 d 1 4 s 0 ; S c 3 + → 3 d 0 ; M n 2 + → 3 d 5 4 s 0 ; Z n 2 + → 3 d 10 4 s 0 In M n 2 + number of unpaired d e - = 5 . So it has maximum magnetic moment according to the formula. μ = n ( n + 2 )
