Homework Help: Bohr's atom model. some doubts

  1. Sep 29, 2010 #1
    1. The problem statement, all variables and given/known data

    revered members,
    one limitation of bohr atom model is that it could not account for distribution and arrangement of electrons. i could not understand this statement, that is, according to bohr , electrons revolve around the nucleus in circular orbits and the necessary centripetal force is provided by the electrostatic force of attraction between the nucleus and the electron. so, electrons are situated around the nucleus. THEN HOW CAN WE SAY THAT HE COULD NOT ACCOUNT FOR DISTRIBUTION AND ARRANGEMENT OF electrons? does electrons in circular orbits around nucleus not mean distribution and arrangement? please help..

    2. Relevant equations



    3. The attempt at a solution

    I'm not sure what particular observations they're referring to, but clearly electrons don't orbit in perfect circles, so the bohr model wouldn't account for their true distributions---i suppose that's what they're referring to. Also the bohr model isn't fully self-consistent....

    Anyway, I don't think the particular wording here is important, the overall message is that the bohr model, while useful, is wrong in the end.
