It has to do with the uncertainty principle.

Copyright © 2010 Ryan P. Murphy It has to do with the uncertainty principle. -The electron cannot have a defined position in the nuclei of atoms means that it must occupy every other space within the atom in a wave of possibilities.

Copyright © 2010 Ryan P. Murphy It has to do with the uncertainty principle. -The electron cannot have a defined position in the nuclei of atoms means that it must occupy every other space within the atom in a wave of possibilities. Pauli exclusion principle: The principle that two fermions of a given type, such as electrons, protons, or neutrons, cannot occupy the same quantum state. It does not apply to bosons. This principle plays a key role in the electron orbital structure of atoms, since it prevents more than two electrons from occupying any given orbital (two are allowed, since they may have opposite spin, and thus be in different quantum states) More difficult explanation.
