The three constituents that make an atom are protons, neutrons, and electrons.
Positive charge particles are called Protons Negatively charged particles are called Electrons Neutrons have no charge Protons was discovered by Ruther Ford Electrons was discovered by JJ Thompson Neutons was discovered by James Chadwick
protons/neutrons are made of quarks which are smaller than electrons. electrons are smaller than protons and neutrons.
