1. Proton: a particle from the atomic nucleus, positive charge, mass approx. 1 u.a.; discovered by Ernest Rutherford in 1919.
2. Neutron: a particle from the atomic nucleus, neutral, mass approx. 1 u.a.; discovered by James Chadwick in 1932.
3. Electron: a particle from the atom, negative charge, very low mass; discovered by
J. J. Thomson in 1932.
These particles are: proton, neutron, electron.
protons, electrons and neutrons
ALL subatomic particles fall into one of those three categories.
Protons, neutrons, and electrons.
They are three different types of subatomic particles.
protons, neutrons, and electrons are the subatomic particles involved with an atom

These particles are: proton, neutron, electron.
You mean subatomic particles. They are proton, neutron and electron.
Three Subatomic Particles: 1) Neutrons- neutral (no) charge. 2) Protons- positive charge (+) . 3) Electrons- negative charge (-) .
Three subatomic particles were discovered in the 1900s: the neutron in 1932, the positron in 1932, and the neutrino in 1956.
The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or Atomic Mass units.

They have a mass and are components of the atom.
There are no particles within an electron: it is a particle unto itself.
There are three: protons, neutrons, and electrons.
