Lone Pairs

Any time there are lone pairs, does that make the compound a nucleophile?

Yes. It is the easiest way to identify a nucleophile.

This is not true 100% of the time. Lone pairs generally make an atom nucleophilic, but the presence of lone pairs in a molecule does not guarantee that it is a nucleophile. For example, H3CBr has 3 lone pairs on the Br, but this molecule acts as an electrophile in the presence of something like OH-.
