The number of radial nodes in $3 s$ and $2 p$ respectively are

Correct answer
A
2 and 0
B
1 and 2
C
0 and 2
D
2 and 1

Solution

Number of radial nodes $=n-1-1$ For $3 s$, radial nodes $=3-0-1=2$ For $2 p$, radial nodes $=2-1-1=0$ Hence, the number of radial nodes are 2 , and 0 respectively.

Hence, the correct answer is option: 'A'.
