Question

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

Explanation:

Step1: Recall the rule for azimuthal quantum number \( l \)

For a given principal quantum number \( n \), the azimuthal quantum number \( l \) can take integer values from \( 0 \) to \( n - 1 \).

Step2: Calculate possible \( l \) for \( n = 3 \)

Given \( n=3 \), then \( l \) can be \( 0, 1, 2 \) (since \( l \) ranges from \( 0 \) to \( n - 1=3 - 1 = 2 \)).

Answer:

0, 1, 2
