Which orbital among the following has zero radial nodes and 2 angular nodes?

Options

  1. A4 ~s
  2. B3 d
  3. C2 p
  4. D5 ~s

Correct answer

B. 3 d

Step-by-step solution

Two angular nodes are found in d -orbital. Number of radial nodes =(n-l-1) So, for 3 d . n=3, l=2 Number of angular nodes =l=2 aligned Number of radial nodes & =n-l-1 & =3-2-1=0 aligned So, 3 d -orbital has zero radial node and 2 angular nodes.
