An alpha particle is approximately 4 times heavier than a proton. It consists of two protons and two neutrons, whereas a proton is just a single subatomic particle.
Neutron: Mass: 1,00866491600(43) amu. Charge: neutral Electron: Mass: 5,4857990946(22)×10−4 amu. Charge: negative Proton: Mass: 1,007276466812(90) amu. Charge: positive
The smallest subatomic particles can be found within the nucleus of an atom. These include protons and neutrons, which are further composed of even smaller particles called quarks.
2 protons, 2 electrons and 2 neutrons

This would be the alpha particle. An alpha particle has two neutrons and two protons, and it's actually a helium-4 nucleus. That's why we write this particle like this: 42He or He+2 Use the links below for more information.
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.
This particle is the electron: 9,10938291(40)×10−31 kg or 5,4857990946(22)×10−4 amu.
6 subatomic particles. 2 protons and 2 neutrons (that accounts for the mass of 4 amu) as well as 2 electrons.
