The number of angular nodes and radial nodes in 3 s orbital are

The number of angular nodes and radial nodes in

3 s

orbital are

$0$ and $2,$ respectively
$1$ and $0,$ respectively
$3$ and $0,$ respectively
$0$ and $1,$ respectively

Solution

No. of angular nodes

= ℓ

No. of Radial nodes

= n - ℓ - 1

For

3 s; n = 3

and

ℓ = 0

∴

No. of angular nodes

= 0

∴

No. of radial nodes

= 2
