The three particles of any atom are
electron) the smallest particle and is held in shells around the nucleus of the atom
proton) is found in the nucleus and is much larger than an electron
neutron) the same mass as a proton and also found in the nucleus of the atom

electron: the negatively charged particles held in orbital shells around the nucleus. They are held in place by protons. Electrons do not effect the atomic weight but they do effect the charge.

proton: the positively charged particles found in the nucleus. Protons do effect the atomic weight and the charge. 

neutron: the particles without any charge found in the nucleus. Neutrons do effect the atomic weight but do effect the charge.
