Pauli Exclusion Principle
		• From quantum rules, electrons don’t like to be packed into a small space, either in atoms or in ionized gas • At normal ionized gas densities, electrons are so spread out quantum rules don’t matter. • As high enough ionized gas densities, quantum rules need to be considered, just has they have been in atoms • Think of each “atom sized” region of space having a set of energy levels associated with it  (although it is really more complicated)
