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

Multiple Choice Options

  • A n = 4, l = 3, m = +1, s = + 1/2
  • B n = 4, l = 4, m = -4, s = - 1/2
  • C n = 4, l = 3, m = +4, s = + 1/2
  • D n = 3, l = 2, m = -2, s = + 1/2

Step-by-Step Verified Solution

For 4f orbital,

n = 4 and l = 3

Note : ( for s orbital l = 0, for p orbital l = 1, for d orbital l = 2, for f orbital l = 3)

Value of m = + l to - l

Here m = +3 to -3

Value of s = +12+ {1 \over 2} or −12- {1 \over 2}
