Light is emitted
In order for an electron to emit a photon is must be:
excited to a higher energy level
ionized from the atom
relaxed to a lower energy state
reverse spin of the electron
If an electron absorbs energy, it is:
elevated from the excited state to the ground state
elevated from the ground state to an excited state
relaxed from the excited state to the ground state
relaxed from the ground state to an excited state

The lines on an emission spectra shows where:
electrons are absorbing specific energies
electrons travel around the nucleus
energy of specific wavelengths
that there is a limited number of energy levels in an electron
