WebFinal answer. A photon with energy 1.88eV is absorbed by a hydrogen atom. (a) Find the minimum n for a hydrogen atom that can be ionized by such a photon. (b) Find the speed of the electron released from the state in part (a) when it is far from the nucleus. km/s. WebAbove this line is the region called "free electrons" in the diagram. This corresponds to an ionized atom. In this range, the energy levels are not quantized -- that is, any energy is possible. So any photon with enough energy to put the total energy somewhere in that shaded region is capable of ionizing the atom. shantee creek toledo
