Recall: The Balmer equation relates the wavelength of a photon from the transition of an electron in an atom. For an absorption process, the Balmer equation is:
where R = Rydberg constant (1.0974 × 107 m–), Z = atomic number, n = energy level.
For an electron in a ground-state H atom (Z = 1), the initial energy level is ninitial = 1. We’re given the wavelength of a photon absorbed by this electron, λ = 97.20 nm. Converting from nm to m:
The electron in a ground-state H atom absorbs a photon of wavelength 97.20 nm. To what energy level does it move?
