When a hydrogen atom absorbs a photon of
*refer to attached image before proceeding*
To ionize a hydrogen atom (forming a hydrogen ion), requires that the energy absorbed is sufficient to send the energized electron an infinite distance away from the nucleus (as shown by the ionization line in the image above). In other words, nfinal is equal to infinity.
Calculate the energy required to ionize a ground state hydrogen atom. Report your answer in kilojoules.
delta E= ____kJ
