As a matter of fact, only alpha particles are actual particles, neither beta nor gamma is particle.

alpha particles are 4He2+ [Helium nuclei]. beta particles, even if we normally called them _particles_, are decay processes and should be called _beta decay_ instead. There are two forms of beta decay, β− and β+, which respectively give rise to the electron and the positron [has the same mass but opposite electrical charge as electron].

β− decay: : p→n + e^- + νe, p is proton, n is neturon, ve is antineutrino, the antiparticle of neutrino. Both electron and antineutrino are released from the atom. β+ follows a similar manner, just no electron but positron is released.

γ -radiation are high energy X ray (EM wave). Emission often accompanies the loss of α-or β particles. The daughter nuclide is often at excited state, transition from excited to ground state simulates γ-radiation to take away the excess energy.

So, the answer should be beta particle.

Recalling from a long time ago, but:

An alpha particle is the same as the nucleus of a helium or 2 protons and 2 neutrons. That is much bigger than an electron.

I think that a beta particle and an electron are the same thing.

And, the gamma particle is just a piece of e-m radiation like an x-ray or a high energy photon.

So, the answer is 'beta'

I am not a physicist but I am answering your question anyway and since I could claim to be a physicist, whats the difference, and don't you think its a little snooty to try to restrict responces to just physicist when there are nuclear engineers out there that might could provide just what you need

although the point of this answer was to tirade, I will tell you that a beta particle has the mass of an electron

tbolling is correct.
Alpha particle contains 2 protons and 2 neutrons. This means, it is an Helium nucleus, and its electric charge is 2+.
Beta is an electron from a radioactive decay. Its electric charge is 1-.
Gamma radiation is only electromagnetic, there is no particle involved.

beta particles are same as electrons but emitted by nutron decay in a nucleus. While neutron gets converted to a proton in a nucleus, it emits an electron and a neutrino...another almost mass less energy balancing particle

Before knowing the nature of beta particles the radiation was named as beta radiations.

Latter it was confimed that they are actually electrons.

Hence beta radiations are not merely 'same mass and electron' but actually they are electrons.

Beta particle is an electron.

A beta particle is an electron.
So it is about beta decay.

I happen to know the answer to this...however I'm not a physicist so...
