Question

What is the number of radial nodes for a 4f orbital?

• A. 1
• B. 0
• C. 2
• D. 3

Hint:

Use the formula: Radial nodes = n - l - 1.

Answer 1

The Correct Option is A

Radial nodes are calculated as n - l - 1. For a 4f orbital, where n = 4 and l = 3, the number of radial nodes is:

4 - 3 - 1 = 1
