THAT’s what I remember from elementary school during the 50s-to-60s transition years! :
Protons and neutron were the same size and surface texture, opaque, but had different colors from each other. We never got to weigh individual examples, but teachers claimed they all weighed the same, more or less...
protons actually weigh slightly less than a neutron. I would hazard a guess that the difference accounts for the neutral vs positive charge.
CHARACTERISTICS OF ELECTRON
Charge: It is a negatively charged particle.
Magnitutide of charge: Charge of electron is 1.6022 x 10-19 Coulomb.
Mass of electron: Mass of electron is 0.000548597 a.m.u. or 9.1 x 10-31 kg.
Symbol of electron: Electron is represented by “e”.
Location in the atom: Electrons revolve around the nucleus of atom in different circular orbits.
CHARACTERISTICS OF PROTON
Charge: Proton is a positively charged particle.
Magnitude of charge: Charge of proton is 1.6022 x 10-19 coulomb.
Mass of proton: Mass of proton is 1.0072766 a.m.u. or 1.6726 x 10-27 kg.
Comparative mass: Proton is 1837 times heavier than an electron.
Position in atom: Protons are present in the nucleus of atom.

CHARACTERISTICS OF NEUTRON
charge: It is a neutral particle because it has no charge.
Mass of neutron: . Mass of neutron is 1.0086654 a.m.u. or 1.6749 x 10-27 kg.
Compartive mass: Neutron is 1842 times heavier than an electron.
Location in the atom: Neutrons are present in the nucleus of an atom.
Isn’t it interesting that as time goes on, and we learn more about the elemental functions of the Universe, the less we actually understand ?
