Which of the following sets of quantum numbers is correct for an electron in 3 d -orbital?

Options

  1. An=3, l=2, m=-3, s=+ 1 2
  2. Bn=3, l=3, m=+3, s=- 1 2
  3. Cn=3, l=2, m=-2, s=+ 1 2
  4. Dn=3, l=2, m=-3, s=- 1 2

Correct answer

C. n=3, l=2, m=-2, s=+ 1 2

Step-by-step solution

For 3 d -orbitals; n=3, =2 . m can take values from - to + , i.e., -2 to +2 . s can take values + 1 2 or - 1 2
