Drawn an orbital overlap diagram to represent the bonding in ammonia, NH3.
The Attempt at a Solution
I learned that bonding occurs with the outermost s and p orbitals.
1s2 , 2s2 , 2p3
1s1 X 3.
This is what I drew
Someone told me to think about the Pauli Exclusion Principle and that my diagram is incorrect because of some of the spin states in the orbitals. The Pauli Exclusion Principle states that each orbital can old 2 electrons. If two electrons are in the same orbital they must have opposite spins. In my diagram, any orbital that has two electrons has opposite spins, so I am not sure what the person was telling me.
