Question

When hydrogen like atom in excited state make a tansition from excited state to ground state most energetic photons have energy emax= 52.224ev?

Answer 1

An excited-state atom is an atom in which the total energy of the electrons can be lowered by transferring one or more electrons to different orbitals. That is, in an excited-state atom not all electrons are in the lowest possible energy levels. eg. Consider a carbon atom whose electron configuration is the following.
