Question

The principal quantum number (n) and azimuthal quantum number (l) for the circular path present in the fourth main energy level are:

• A. n = 4, l = 1
• B. n = 4, l = 2
• C. n = 4, l = 3
• D. n = 4, l = 4

Answer 1

Answer: (A), (B), (C)

n = 4, l = 1
n = 4, l = 2
n = 4, l = 3

For fourth main energy level $n=4$ and $l=3,2,1,0$. So, D is the only incorrect option.
