Quantum mechanics

  1. Feb 2, 2007 #1
    Hey people,

    I have beeno wondering this for a while:

    If the nucleus of an atom is positively charged and the electrons are negatively charged, why don't the electrons stick to the nucleus like a magnet, why do they only have a certain distance between themselves.

    If the electrons are constantly rotating around the nucleus, this means that a change in direction would cause an accelartion of the electrons. For something to accelerate it needs energy or a force. Where does this energy comes from and why it is not extinguised over the time

    I guess the reason that (negative) electrons will not stick to the (positive) nucleus is because between the nucleus and the electrons, there actually exists a strong 'force' that prevents the electrons from sticking to the nucleus. Another reason will be that elecrons orbit around the nucleus in electron shells. So, there is no way that the electrons will stick on the nucleus.
