Chemistry Question on Quantum Mechanical Model of Atom

The number of angular nodes and radial nodes in 3s3s orbital are

A

0 and 2, respectively

B

1 and 0, respectively

C

3 and 0, respectively

D

0 and 1, respectively

Answer

0 and 2, respectively

Explanation

Solution

No. of angular nodes = ℓ\ell

No. of Radial nodes =n−ℓ−1=n-\ell-1

For 3s;n=33s ; n=3 and ℓ=0\ell=0
∴\therefore No. of angular nodes = 0

∴\therefore No. of radial nodes = 2
