An electron in an atom will only become excited if a photon of exactly the right amount of energy strikes it. That energy can be found using the formula: An electron in an atom will only become excited if a photon of exactly the right amount of energy strikes it. That energy can be found using the formula:
$$\Delta E=hf$$ $$\Delta E=hf$$
where $E$ is the energy of the photon at frequency $f$, and $h$ is Planck's constant ($\pu{6.63\times 10^{-34} Js}$ or $\pu{4.14\times10^{-15} eVs}$). where $E$ is the energy of the photon at frequency $f$, and $h$ is Planck's constant ($\pu{6.63\times 10^{-34} Js}$ or $\pu{4.14\times10^{-15} eV/Hz}$ or $\pu{6.58\times10^{-16} eVs}$).
An electron that de-excites will emit a photon of that exact energy and thus frequency to return to its previous state. An electron that de-excites will emit a photon of that exact energy and thus frequency to return to its previous state.
