Question

The possible number of radial nodes for 2p and 2s subshells , respectively, are.

(A)1,0
(B)0,1
(C)1,1
(D)0,3

Answer 1

Answer:

Correct option is

B

2,0

The number of radial nodes of 3s and 2p orbitals respectively are 2 and 0 respectively.

Number of radial nodes =n−l−1

For 3s orbital, number of radial nodes =3−0−2=2

For 2p orbital, number of radial nodes =2−1−1=0

Hence the correct option is B.

Answer 2

Answer:

0, 1
