Hydrogen atom does not emit X-rays because

Options:

It has signal electron

It has no neutron

It has single neutron

Its energy levels are too close to each other

Correct Answer:

Its energy levels are too close to each other

Explanation:

X Ray is emitted when energy gap between energy level is of the order of KeV. But in case of hydrogen atom maximum energy gap is 13.6 eV.
