Pre-Lab: Experiment 6; The Atomic Spectrum of Hydrogen The helium ion, He", has simple energy levels similar to those of the hydrogen atom since both have only one electron and the electron energy levels of the He" ion can be calculated by the equation: En = -8.715 x 10-8 J (per photon) n 1. Calculate the energies of the four lowest energy levels of the He* ion. E E = Es= E4= 2. Find the energy value of the transition from n-4 to n=1. Find the wavelength of the photon emitted when this transition occurs. 3. Three of the strongest lines in the helium ion spectrum are at 121.6 nm, 164.1 nm, and 25.64 nm. Find the quantum numbers of the initial and final states for the transitions that produce these lines. (Hint: First calculate the energy of these lines and then comparing them to the transitions involving any two of the four lowest levels.) (1)- (2) (3)
