An HCl molecule contains 3 nonbonding pairs..
There are four electrons, which is two pair.
Ammonia contains N and H atoms. There are 3 bonding pairs.
There are three bonds between Nitrogen and hydrogen and there are thus 3 shared bonding pairs of electrons. in addition since Nitrogen is 1s22s22p3 there are also the none bonding 1s2 electrons and the 2s2 electrons making 5 total shared pairs of electrons.

Dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule.
There are three bonds between Nitrogen and hydrogen and there are thus 3 shared bonding pairs of electrons. in addition since Nitrogen is 1s22s22p3 there are also the none bonding 1s2 electrons and the 2s2 electrons making 5 total shared pairs of electrons.
There are three bonding pairs of electrons in BF3. There are 0 nonbinding pairs, but BF3 can accept two more electrons to give it a complete octet
Methane has a tetrahedral molecular geometry. It has 4 bonding pairs of electrons and no lone pairs.
How do lone pairs around the central atom affect the polarity of the molecule?
