    The energy of an electron in an atom is negative. The negative sign indicates that we need to give the electron energy to move it from the hydrogen atom.
    <br>When the electron transits from an excited state to its lower energy state, it will give off the same amount of energy needed to raise to that level. This emitted energy is a ...
