Additional Problems

1) Following up on question 41 above, calculate the wavelength of light associated with an n = 6 to n = 5 transition in a He⁺ ion. In what part of the electromagnetic spectrum does this wavelength fall? Give an example of an electronic transition of He⁺ that would result in the emission of a photon of visible light and indicate what the corresponding wavelength would be.

2) Calculate the ionization energy (in eV) of a hydrogen atom in the n = 5 quantum state.  (from DeKock & Gray: Problem 1-3)
