    i know the quantum numbers n,l,m where n goes from 1 to infinite, and l goes from 0 to n-1 and m goes from -l to +l. My question is if u know this numbers how do u calculate the energy teh electron have in its orbit around the atom?

    For hydrogen the energy of an electron relates to the principle quantum number by



    at least for large spectral structure.

    For more complex atoms you dont have a closed form solution for the wave equation so the energy is calculated numerically to my knowledge.


    As is often the case with technical subjects we are presented with an unfortunate choice: an explanation that is accurate but incomprehensible, or comprehensible but wrong.

    thats for hydrogen, but i want to know for larger more complex atoms

    For larger, more complex atoms, there is simply no simple way of putting it as it is above. It is like asking someone to write down the formula for the motion of three or more bodys under the infuence of gravity. Only rough approximations exist.

    im happy with somekinda approximate, but aslongest its not bohr related cause thats famous for only working on hydrogen like atoms, helium+1 ion and such

    For some kind of approximation you attempt to solve on a computer, and read off the energy levels from the numerical solution. Unless you want to try some aweful perturbation attempt at a solution thats the best you are going to get.

    hmm.. energy in an electron.. has to do with it's path (the further the more energy it has)

    and lightspeed (the speed the electron travels theoreticly)

    and ofcourse the number of electrons in what pathway.

    i bet ya already knew this though.. i'm not good with formula's..
    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..
