A Rydberg atom is one in which an electron is in a very high excited state (n 40 or higher). Such atoms are useful for experiments that probe the transition from quantum- mechanical behavior to classical. Furthermore, these excited states have extremely long lifetimes (i.e., the electron will stay in this high excited state for a very long time). A hydrogen atom is in the n47 state. (a) What Is the lonization energy of the atom when it is in...
