Bohr Model?

Question

A photon is emitted when an electron drops through energy levels within an excited hydrogen atom. What is the maximum energy the photon can have?

If this same amount of energy were given to an electron in ground state in a hydrogen atom, what would happen?

Answer 1

The maximum energy you can get is from a transition from the highest energy state to the lowest energy state. The highest state is 0 eV and the lowest is -13.6 eV (ground state), so 13.6 eV is the maximum energy you can get.

Giving an electron in the ground state of hydrogen this much energy is enough to free it from the atom and ionize the atom itself.
