We’re being asked to determine the value of n for the energy level to which the electron relaxed emitting light of 397 nm.
We’re going to use the Balmer Equation which relates wavelengths to a photon’s electronic transitions.
λ = wavelength, m
R = Rydberg constant = 1.097x107 m-1
Z = atomic number of the element
ninitial = initial energy level
nfinal = final energy level
Calculate the final energy level (nfinal):
An electron in the n=7 level of the hydrogen atom relaxes to a lower energy level, emitting light of 397 nm. What is the value of n for the level to which the electron relaxed?
