Quick Answer. The three parts of an atom are the protons, neutrons and electrons. Atoms make up the basic building blocks of matter and define the structure of elements. These parts were not officially identified until 1932.
I'm guessing that the question is asking what the specific parts of an Atom are. Simply, an atom is composed of protons (positively charged) neutrons (with no charge) and elec â¦ tions (negatively charged). The protons and neutrons form the nucleus. The electrons are on an outer 'ring'.
