Protons and neutrons comprise the nucleus. Both protons and neutrons and made up of three quarks, a type of elementary particle. So yes, elementary particles, building blocks of matter, reside in the nucleus of an atom.

This is the rules, and it is strictly enforced:

Re: elementary particles --their place in atom

The question is ambiguous. It could mean either:

1] Do elementary particles reside inside the nucleus on their own (as opposed to part of another structure)?
2] Do elementary particles reside inside the nucleus only (as opposed to also residing elsewhere)?

Can you rephrase?

Oh, sorry. I didn't even notice this was in the "homework help" section- I just felt like it was more of a factual than logical or mathematical question... no real way to figure out the answer without knowing a bit of information, and no real thought needed once this information was known. I'll pay more attention next time.
