The sum of number of angular nodes and radial nodes for 4d orbital is:
Show Hint
- 2
- 3
- 4
- 5
The Correct Option is B
Solution and Explanation
For a 4d orbital:
The angular nodes for \( l = 2 \) is \( l = 2 \). The radial nodes are given by \( n - l - 1 \), so for \( n = 4 \) and \( l = 2 \), the radial nodes are \( 4 - 2 - 1 = 1 \). Thus, the total number of nodes is \( 2 + 1 = 3 \).
