An alpha particle, boom.
alpha: mass 4, charge +2beta: mass ~1/1800, charge -1gamma: mass 0, charge 0
protons --- rel. mass 1 amu, rel. charge +1, location in the nucleus. neutrons --- rel. mass 1 amu, rel. charge 0, location in the nucleus. electrons --- rel. mass 0 amu, rel. charge -1, location outside the nucleus.
No, an alpha particle has a mass of 4 amu and a charge of +2. It is a helium nucleus. The neutron has a mass of 1 amu and no charge.
The mass of an alpha particle is approximately 4 amu (atomic mass units).

Alpha radiation consists of particles with a charge of +2 and a mass of 4 amu, equivalent to a helium nucleus. Beta radiation consists of particles with a charge of either -1 or +1 and negligible mass, corresponding to electrons or positrons.
Proton.
An electron has a negative charge and a mass close to 0 amu (atomic mass unit).
The electron has a charge of -1; but the electron has a mass.
