Assertion: A hydrogen atom cannot absorb...

Assertion: A hydrogen atom cannot absorb a photon whose energy is greater than `13.6 eV`, its binding energy.
Reason: The extra energy will manifest as `KE` of the electron.

A

If both assertion and reason are correct and reason is a correct explanation of the assertion.

B

If both assertion and reason are correct but is not the correct explanation of assertion.

C

If assertion is correct but reason is incorrect.

D

If assertion is incorrect but reason is correct.

Text Solution

Verified by Experts

The correct Answer is:
C
Assertion is true. A hydrogen atom ionises when it absorbs a photon of energy greater than 13.6 eV because the energy of photon is greater than binding energy of hydrogen atom, which is 13.6 eV.
