Beta particles (electrons) are less massive than alpha particles (Helium-4 nuclei), by a factor of approximately 8000.

Definition for Radioactive decay?
Radioactive decay is the characteristics of radioactive substances that all radioactive atoms do not disintegrate at once but do so gradually .It is spontaneous and it is not influenced by external conditions such as temperature, pressure , etc.. In any radioactive decay , either an alpha particle or beta particle is emitted by atom .Both the particles are not emitted simultaneously .Moreover , the atom does not emit more than one alpha particle or more than one beta particle at a time
What particles come out of radioactive decay?
The primary particles emitted from radioactive decay are alpha particles and beta particles.Alpha particles are helium nuclei, two protons and two neutrons.Beta particles comes in two flavors. In Beta- decay a neutron is converted into a proton, resulting in a W- boson, which then nearly immediately decays into an electron and an electron antineutrino. In Beta+ decay, a proton is converted into a neutron, with the emission of a positron, and an electron neutrino.Sometimes, more than just alpha particles are emitted, in a process called cluster decay, of which alpha decay is simply a subset. You can have multiple alpha particle emission, or you can have substantially larger particles emitted, such as the nuclei of Cesium-137, as a result of fission. While fission is normally an induced process, in nuclear reactors and bombs, it can also spontaneously occur, so it can also be called a decay process.Another particle that can be emitted during fission, spontaneous or induced, is the neutron. Under the right conditions, these neutrons can go on to induce further fission, in a process we call a chain reaction. Controlled, we call that a nuclear power plant; uncontrolled, we call that a bomb.Last, there is gamma radiation or x-rays. Most decay processes leave the nucleus or electron cloud in an excited state, and it "wants" to lose its excess energy and return to normal state. When this happens, a photon is emitted, resulting in gamma radiation (nucleus) or x-rays (electron cloud) of various energies. Most of the time, this photon emission occurs very quickly, on the order of 1 x 10-12 seconds after excitation, but some nuclei, such as Technetium-99m, have a meta-stable state that allows them to stay excited for a long time, usually minutes or hours.
Nuclear decay is the change of an atom of...?
... an unstable isotope to a more stable isotope by emission of some type of radiation (alpha, beta, or gamma).
What are the three main types of radioactive decay?
AlphaBetaGamma!
What radioactive decay of uranium?
The nucleus is too large to be stable. There is the theory of grouping of nucleons into alpha particles inside the nucleus and, through oscillations of the nucleus, one of these on one end of the nucleus can be repelled with a great enough force to push it out of the nucleus.

If the mixture of electrically neutral how many more beta particles than alpha particles are in the balloon?
alpha particles would have twice as many beta particles
How does the penetrating ability of gamma rays compare with that of alpha particles and beta particles?
Gamma rays are more penetrating than alpha and beta particles.
Why are reactions that emit alpha particles generally considered more safe than those that emit beta particles?
Alpha particles are actually electron-less helium nuclei versus beta particles which are actually electrons, which are much smaller than alpha particles. Therefore, alpha particles' penetrating strength is much smaller than beta particles (a sheet of paper versus a wooden board). Therefore, beta particles will penetrate more into a human body and will do more damage than alpha particles which are usually stopped at the skin.
Why were a few alpha particles reflected at large angles?
yes it is
Why do alpha and beta particles cause more damage if they are inside the?
Because alpha and beta particles do not have enough power to pass into the body, but they do more damage than gamma rays once they are inside the body.
Why are alpha and beta rays deflected in opposite directions in a magnetic field?
An alpha particle, which is a 24He nucleus, has a mass of 4 and a charge of +2. A beta particle has a charge of +1 or -1, depending on whether it is a positron (beta +) or an electron (beta -). It's mass is minuscule compared to the alpha particle, and it will undergo a comparatively huge deflection in the same field as an alpha particle would. Though the alpha particle has twice the charge as a beta particle, it has several thousand times the mass of that beta particle. As it is so much more massive than the beta particle, its inertia will be much more difficult to overcome even though it has twice the charge.
Why does it take stronger magnetic fields to move the beam of alpha particles compared to beta particles?
Because the charge on an alpha particle is 2 times stonger then on a beta particle, however, it the alpha particle is 7,350 times more massive (so it takes more force to move it the same distance).
What type of radiation from the nucleus is more penetrating than either alpha or beta particles?
Gamma radiation
Why alpha particles tend to produce more ions than beta particles or gamma rays when they pass through matter?
Alpha particles have a high ionizing power beacaue they have a great linear transfer of energy.
Why are alpha particle tracks observed in a cloud chamber much shorter than beta particle tracks though they emerge from a radioactive sample with almost the same speed?
Alpha particles have a mass of about 4 and a charge of +2, while beta particles have a mass of about 5x10-4 and a charge of -1. As such, the alpha particle interacts much more easily than the beta particle, and spends its energy more quickly.
Why do alpha particle have higher ionizaion energy than beta particle?
Alpha particles are far more massive. Alpha particle is an (ionized) helium atom, a beta particle is just an electron.
