Question

The number of angular and radial nodes of 4d orbital respectively are :

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

Answer 1

The correct option is D 2, 1

For 4d orbital, $n=4$ and $l=2$.

Number of radial nodes $=n-l-1=4-2-1=1$

Number of angular nodes $=l=2$.

The number of angular and radial nodes of 4d orbital are 2 and 1 respectively.
