The Pauli Exclusion Principle tells us that no two electrons in an atom can have the same four quantum numbers. For an electron in the 2p orbital shown above, enter a possible value for each quantum number. n= mı = Give ONE example. mg = Give ONE example. Though a given electron only has one value for m, there are __ possible m values for electrons in 2p orbitals. The Pauli Exclusion Principle tells us that no two electrons in...
