An alpha particle has approximately 4 times the mass of a proton.
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
This particle is the electron with a mass of 5,485 799 094 6(22)×10−4 amu.
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.
