Conversation so far:
where are all particles found in an atom
Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom.
where are protons and neutrons found in an atom
Protons and neutrons are found in the nucleus.
what is the function of electrons in atoms
Electrons are the negatively charged particles of atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons.

Question: what about protons
Self-contained rewrite: what is the function of protons in atoms
