Which of the following sets of quantum numbers is correct for an electron in 4 f orbital?

Options

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

Correct answer

B. n =4, =3, ~m ₁=+1, ~m _ s =+1 / 2

Step-by-step solution

For a 4f- orbital, n=4 and 1=3 For a given value of l , there can be (2 l+1) values of m _l ranging from -l to +l . Thus, m _l=+1 is possible. m _ s can be + 1 2 or - 1 2
