I gave 100 points and will give brainest A photon of visible light can be emitted when .
a. an excited electron jumps down to ground state
b. a ground state electron absorbs energy
c. a ground state electron jumps to a higher energy level

Put these steps in order.

Excited electron becomes unstable.
Ground state electron jumps to a higher energy level.
Electron returns to ground state.
Ground state electron absorbs a quanta of energy.
Excited electron releases energy in the form of a photon.
