The Bohr model can be applied to singly ionized helium He+ (Z = 2). Using this model, consider the series of lines that is produced when the electron makes a transition from higher energy levels into the = 4 level. Some of the lines in this series lie in the visible region of the spectrum (380−750 nm). What are the values of for the energy levels from which the electron makes the transitions corresponding to these lines? We were unable...
