Question

The number of radial nodes and angular nodes in a 4f orbital are respectively:

• A. 0, 3
• B. 1, 2
• C. 2, 1
• D. 2, 0

Hint:

Radial nodes = \( n - l - 1 \), Angular nodes = \( l \)

Answer 1

The Correct Option is A

Radial nodes = \( n - l - 1 \), Angular nodes = \( l \)
For 4f: \( n = 4, l = 3 \)
\[ \text{Radial nodes} = 4 - 3 - 1 = 0, \quad \text{Angular nodes} = 3 \]
