The principle quantum number of an electron is 3.The possible magnitudes of the orbital angular momentum,L,are
E)None of these is correct.

Question

Quizplus · Accepted Answer

The possible values of L for a given principal quantum number (n) are from 0 to (n-1). Therefore, for n=3, the possible values of L are 0, 1, and 2. Option B (1) is the only one that falls within this range. The other options either exceed the maximum value of L or are less than 0.
