a) culate the first 3 electronic energy levels for He' and sketch an energy diagram for these levels. (this does not need to be to scale). b) Then label an electron relaxing from n = 3 to n = 2 on the energy diagram and calculate the energy of the photon that would be released. c) Based on the data collected during the atomic spectra lab, determine whether the photon emitted in the visible spectrum. Note, for He*, E = -2.18E-18 J * (4/n^2)
