Statement I : When a electron in a hydrogen like atom is excited to n = 4 state, radiations of six different frequencies can be emitted.
Statement II : Whenever an electron jumps from one orbit to another orbit it emits energy.

A

Statement I is True, Statement II is True, Statement II is a correct explanation for Statement I

B

Statement I is True, Statement II is True, Statement II is not a correct explanation for Statement I

C

Statement I is True, Statement II is False.

D

Statement I is False, Statement II is True.

Verified by Experts

The correct Answer is:
C

The six different radiations correspond to

`E_4 -E_1`
`E_4 - E_2 , E_2 - E_1`
`E_4 - E_3 , E_3 - E_1`
`E_3 -E_2`
Whenever the electron jumps from `E_4` to `E_1` either directly or in steps `E_4` to `E_3` to `E_2` to `E_1` a characteristic radiation is emitted.
The reason is not correct as the electron does not emit radiation when going from any lower orbit to any other higher orbit. The electron will emit radiation only when going from a higher to a lower orbit nor from a lower orbit to a higher orbit.
