Pauli Exclusion Principle
... Electrons in a single atom occupy discrete levels of energy. No two “energy levels” or “states” in an atom can have the same energy. Each energy level can contain at most two electrons -- one with “clockwise spin” and one with “counterclockwise spin”. If two or more atoms are brought together, their ...

... between N and H. But the N "wants" the electrons more than the H does, so it pulls them closer to itself. You end up with a little more than half the negative charge from the bond on the N, and a little less than half on the H. That means N has a partial negative charge and H has a partial positive ...
