Answer to Question #116146 in General Chemistry for SOPHIA

Question

Consider only transitions involving the n = 1 through n = 4 energy levels for the hydrogen atom (using the diagram below).


How many emission lines are possible, considering only the four quantum levels?

Photons of the lowest energy are emitted in a transition from the level with n =
to a level with n =
.

The emission line having the shortest wavelength corresponds to a transition from the level with n =
to the level with n =

Answer 1

The energy that is gained by the atom is equal to the difference in energy between the two energy levels. ... The electron energy level diagram for the hydrogen atom. He found that the four visible spectral lines corresponded to transitions from higher energy levels down to the second energy level (n = 2)

It has one electron attached to the nucleus. The energy in a hydrogen atom depends on the energy of the electron. When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level.
