Ammonia NH3 one lone pair on Nitrogen, Water H2O two lone pairs on Oxygen.
The molecular geometry of a compound helps to determine polarity because, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs because if there are no lone pairs on the central atom, them it is non-polar).
one can find the bond pairs by finding the oxidation state on the central atom
Boron trichloride is an inorganic compound that is a valuable reagent in organic synthesis. It has zero lone pairs on the central atom.
No lone pairs
Every pair of electrons on the central atom (S) of the Lewis structure of SF6 is shared by an F atom, so therefore there are no lone pairs on the central atom.

There are no lone pairs and it's tetrahedral.
Ammonia NH3 one lone pair on Nitrogen, Water H2O two lone pairs on Oxygen.
The Central atom has no lone pairs in CH4
One on each side (at 180º) of the central atom.
