neutral charged nucleophile

How do you know if something is a nucleophile if it is not negatively charged? For example, NH3?

A molecule with an extra lone pair can also be a nucleophile even though it isn't charged. NH3 has three bonds and a lone pair. The lone pair is a region of electron density which is negative. The lone pair could be used to form a bond with a positive (or partially positive) molecule.

Also, molecules with double or triple bonds are nucleophiles even though they may be neutrally charged because the double and triple bonds are electron rich regions.
