# Solution: The electron in a ground-state H atom absorbs a photon of wavelength 97.20 nm. To what energy level does it move?

###### Problem

The electron in a ground-state H atom absorbs a photon of wavelength 97.20 nm. To what energy level does it move?

###### Solution

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: View Complete Written Solution
