The sum of number of angular nodes and radial nodes for 4 d orbital is

The sum of number of angular nodes and radial nodes for 4 d orbital is
  1. 2
  2. 3
  3. 4
  4. 5

Solution

Radial node $=\mathrm{n}-l-1$
Angular node $=l$ $\therefore$ for 4 d $\mathrm{n}=4, l=2$ Angular node $=2$ Radial node $=4-2-1=1$ Sum of angular + radial node $=3$
