[QUOTE="David Gould, post: 643532, member: 2866"] In the classical model, ignoring Maxwell for the moment, the electron does not crash into the nucleus because it has velocity which is not straight at the nucleus As such, it cannot crash into the nucleus but will simply orbit forever. Maxwell's laws complicate this a little, because a moving electrically charged particle will radiate energy away from itself, eventually losing velocity and spiralling into the nucleus (with 'eventually' meaning a fraction of a second.) That it does not do this is because energy is quantisized. This means that if an electron is to radiate energy away it has to do so in huge lumps - the energy of a photon. Using Maxwell's laws, the energy that an electron would lose in any orbit simply from its orbital movement is significantly less than the energy of a photon. Thus, as it cannot radiate away that energy, it does not, and thus remains in orbit around the nucleus. This is what quantum physics is all about - the quantum (the unit) of energy that an electron can radiate or absorb, and which switches it in orbits (now called 'energy levels') around the nucleus. I have been to Dr Dino's site many times. It is a load of nonsense. I hope that you will do some reading about this - I have taken significant time to try and explain stuff, and others have taken even longer. I also hope that you are honestly intrigued by the workings of the atom - it is a very interesting area of study. [/QUOTE]
