Statement : electromangetic radiations w...

Statement : electromangetic radiations will be emitted for the transtition of ` 2p` to` 2s` orbitals in H-atom .
Explanation : Both have same energy level and thus no transition .

A

S is correct but E is wrong

B

S is wrong but E is correct.

C

Both S and E are correct and E is correct explanation of S

D

Both S and E are correct but E is not correct explanation of S

Text Solution

Verified by Experts

The correct Answer is:
B
In H-atom energy for an orbital is decided by 'n' only and not by 'l'.
