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

Options

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

Answer

C

Explanation

For 4 f-orbital
`n = 4, lk = 3, m = -3, -2, -1, 0, +1, +2` or `+3`
`s = +1//2` or `-1//2`
`:.` Correcty choice is (C ).
