Which orbital has only positive value of wave function at all distances from the nucleus :

A

1s

B

2p

C

2s

D

3d

Text Solution

Verified by Experts

The correct Answer is:
A
None is the point at which the wave function changes from positive to negative. 1s orbital has no node hence its wave function will not change from positive to negative.
