Question

Quantum Numbers.

A) If n=4, then l should equal to 4 also. So what would ml be?

B) If n=9, then 1 should equal to 9 also. So what would ml be?

For A) ml I get 9 and B) ml to be 19. Are these right?

Answer 1

A. If n=4, then l can't be larger than 3 (n-1); therefore, ml can be

-3, -2, 0, +1, +2, +3.

Use the same reasoning for B.
