Question

Which of the following can be the quantum numbers for an orbital?

(a) n = 4, l = 4, m = 3

(b) n = 2, l = 3, m = 1

(c) n = 3, l = 2, m = -1

(d) n = 3, l = 0, m = -3

I had been asked this question in examination.

The origin of the question is Electron Probability Density in portion Quantum Physics of Engineering Physics I

Answer 1

Right option is (c) n = 3, l = 2, m = -1

To elaborate: In the given options, option n = 3, l = 2, m = -1 is the correct option because in this the value of l is between 0 – n-1 and value of m is between –l to +l.
