Alpha particles (helium nuclei) are much larger and heavier than beta (electrons) and gamma (high-energy photons). This means they do far more damage to anything they hit.
However, it also means can't travel very far and can be stopped by as little as a sheet of paper.
Radioactive isotopes that emit only alpha radiation are not very dangerous, the only danger is breathing in or ingesting the isotope.
No. The alpha particle is about four times more massive than a neutron.
No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons. Therefore, an alpha particle has approximately 4 times the mass of a proton or neutron.No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons.

An Alpha particle is composed of two protons and two neutrons, so simplisticly it is heavier than one neutron by the mass of two protons and one neutron. A proton weighs in at 1.672621777(74)×10−27 kg and a neutron a bit more at 1.674927351(74)×10−27 so you can do the maths if u want to see the actual figure.
process by which a target nucleus can be split into two smaller nuclei upon bombardment
The masses of all three particles are different The masses of a proton and the mass of a neutron are very close, however. The mass of an electron is much smaller than the mass of a proton or neutron.
An alpha particle is a helium nucleus, consisting of 2 protons and 2 neutrons. Beta particles are fast moving electrons that are emitted from a nucleus when a neutron decays into a proton and an electron. Since 1 electron has 1/1837 the mass of a proton, the alpha particle is roughly 7348 times the mass of the electron.

Electron!
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.
among these Electron has the least mass....

the neutral or no charge particle of an atom:it is located in the nucleus;has the same mass as the proton.
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.

An alpha particle has the charge 2+ and the mass 4.
