Question

which set of numbers gives the correct possible values of l for n = 2?
0
0, 1
0, 1, 2
0, 1, 2, 3

Explanation:

Step1: Recall the relationship between n and l

The angular - momentum quantum number l ranges from 0 to n - 1 for a given principal quantum number n.

Step2: Calculate the possible values of l for n = 2

When n = 2, l can take values l=0 and l = 1 since l ranges from 0 to n - 1 (2-1 = 1).

Answer:

0, 1
