Alpha decay:- It is a process of disintegration of an element which involves formation of a new element by loosing an alpha particle(He2+).
Example:-
84Po214 --------->82Pb210 + 2He4 + Q
Where subscripts denote atomic number, Superscripts denote Atomic Mass and Q is the energy released in the process.
Beta Decay:- It is also a process of disintegration but the difference from alpha decay lies in the fact that an electron is given out in the process rather than alpha particle.
Example:-
0n1 ----->1p1 + -1e0 + anti-neutrino.
Where n is neutron, p is proton, e is electron, subscripts are atomic charge and and superscripts are atomic mass.

Which of these masses is the largest alpha particle antineutrino gamma radiation beta particle?
Alpha Particle
Breaking down of a neutron into a proton and an electron?
When a neutron breaks down into a proton and electron it is called decay. In this specific case it is Beta - (minus) decay since it is producing an electron (it also produces an electron antineutrino). If the result were a positron instead of an electron it would be called Beta + decay. Since a new proton has been made the element is also changed into the next highest element on the periodic table. So for instance, Carbon 14 will beta- decay into Nitrogen 14. Both types of Beta decay are mediated or assisted by the weak nuclear force with the W- and W+ bosons.
What symbol is used for a neutrino particle?
Beta particle symbols: e- or β- or B- (electrons) or e+ or β+ or B+ (positrons). If the - or + sign is omitted, assume that the beta particles are electrons. The Greek beta character is usually preferred, but a B is acceptable if Greek fonts are not available.
Is there a positron in the nucleus of an atom?
There are no positrons in the nucleus of any atom. Positrons are anti-electrons; they are antimatter. They could be said to be the antimatter equivalent of the electron, and, as such, they would be present around the nucleus of an antimatter atom as the electrons are present around the nucleus of a "regular" atom. Positrons can be produced in atomic nuclei by some kinds of radioactive decay, and they can be observed to be leaving a nuclear reaction called beta plus decay. But the positron leaves the nucleus of an atom as soon as it is created. It does not (cannot) exist in the nucleus of an atom.
What is released when a proton and electron are forced together?
This is called inverse beta decay and it forms a neutron. Normally a neutron will decay into a proton and electron, but the opposite will happen given enough energy. Coincidentally, this is how neutron stars are formed (the immense pressure from gravity overcomes the force separating protons and electrons.)
Order gamma decay beta decay and alpha deacy form weakest to strongest?
gamma decay beta decay alpha decay
How were Alpha decay and beta decay discovered?
Alpha, beta, and gamma radiation were first observed from a sample of Radium in a magnetic field.
What is the beta decay of radium 226?
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
What correctly describes the charge of beta particles and alpha particles?
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.
What are the products of radioactive decay?
alpha decay, beta decay, and gamma radiation
Alpha and beta decay emit what?
radiation
What is mass converted to in nuclear processes?
nuclear decay, such as alpha decay or beta decay.
What are the three products of radioactivity decay?
alpha decay, beta decay, and gamma radiation
How is the atomic number of a nucleus change is it by alpha decay or beta decay or gamma decay?
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
What is the nuclear equation for the alpha decay of uranium 239?
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
What are the possible products of the alpha decay of uranium-238?
The only possible product of the alpha decay of 92238U is 90234Th.
What is the equations for the beta decay of radon-198?
Radon-198 does not decay via beta decay. It is thought to decay by alpha decay, but that is not certain. The equation would be ... 86198Rn -> (Alpha, T1/2 = 86 ms) -> 84194Po + 24He2+
