    Why can electrons only occupy certain energy levels?
    What does it mean by electrons absorb a particular frequency of radiation? Does it mean they only absorb some radiation to get to higher energy levels but not too much as that will ionise and remove them from the atom?

    I know a book which would be useful to you. It's called "fundamentals of analytical chemistry (Author: skoog)". I don't know if you are a university student because if you aren't, maybe this book would be a bit complex for you

    electrons can exist at different energy levels in an atom - when an electron jumps down to a lower energy it gets rid of energy by emitting a photon and in the reverse process it can absorb a photon of the correct energy and jump up to a higher energy level in the atom.
    photon energy is related to photon frequency - higher energy photons have higher frequency (and higher frequency of course means shorter wavelength)

    Yes but what does the frequency depend on meaning if they wanted to jump into a higher energy level, they would jump at a higher frequency to do so? What I meant was depending on if they are absorbing or emitting, what would the frequencies be, higher when absorbing and lower when emitting?

    It's the same photon frequency when absorbing or emitting.
