| 349437 | 2005-04-27 13:48:00 | Greetings people, could someone explain to me in as plain English as possible on what's Pauli exclusion principal? I know the basics of atom, however. Cheers :) |

| 349440 | 2005-04-27 14:14:00 | This is somewhat beyond my memory of first-year physics, but hopefully I can explain it. "No two electrons in an atom can have identical quantum numbers. This is an example of a general principle which applies not only to electrons but also to other particles of half-integer spin (fermions). It does not apply to particles of integer spin (bosons)." from: hyperphysics.phy-astr.gsu.edu quantum number definitions: hyperphysics.phy-astr.gsu.edu Basically, this is saying that no two electrons can have the same *set* of quantum numbers (spin which is either half up or half down,two angles and a radius as diagrammed on my second link), which limits the number of electrons in a given state - if Pauli's exclusion principle *didn't* hold, then there would be no limit to how many electrons could drop into the K shell around a nucleus.

| 349441 | 2005-04-27 14:26:00 | en.wikipedia.org I understood almost nothing from Wikipedia's explanation on Pauli Exclusion Principal. That's why, I ask for as plain English as possible. :annoyed: I guess I can only blame my ownself. |
