Draw a representation of an electron going from ground state to excited state and back to ground state. Make sure to include where energy is given off/absorbed.
Ground state (regular, lowest energy state) -> (Energy is input) -> Electron jumps up in orbit (Excited state) -> Electron jumps DOWN in orbit -> (Energy is given off as light)
