Question
Which atomic orbital has quantum numbers n = 4 and l = 2?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The angular momentum quantum number l designates the orbital type: l = 0 (s), l = 1 (p), l = 2 (d), and l = 3 (f). For n = 4 and l = 2, the orbital is designated as 4d.
Hint
Recall the letter designation corresponding to each l value: s for 0, p for 1, d for 2, f for 3.
