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

A

`0`and`2`

B

`1`and`2`

C

`2`and`0`

D

`2`and`1`

Text Solution

Verified by Experts

The correct Answer is:
C
The number of radial nodes or spherical nodes is given by the formula
`n - l-1`
where `n` is principle quantum number and `l` is azimuthal quantum number.
For `3s` orbital, `n - l-1 = 3-0-1=2`
? For `2p` orbital, `n - l - 1=2 - 1- 1=0`
