Alpha or an He nucleus because it has a mass of 4 when all the others have a mass of close to zero.
Alpha radiation involves the ejection of a helium nucleus, which has a mass number of 4. This results in the largest change in mass number compared to beta and gamma radiation, which involve the emission of electrons or photons with much smaller masses.
this actually really funny because im looking for the same answer but i believe that the answer is a chemical activity is undergoing a chemical change while radioactivity is emission of radition
Gamma decay involves the emission of a gamma ray, which is a high-energy photon with no charge and no mass.
Alpha radiation is the smallest type of nuclear radiation consisting of helium nuclei (2 protons and 2 neutrons). Due to its large size and positive charge, it penetrates materials poorly and is stopped by a sheet of paper or the outer layer of human skin.
Usually with the '4 types of radiation' it is referred to:- alpha radiation (emission of an alpha particle = a helium nucleus = 2 neutrons + 2 protons):Hence for the emitting nucleus the mass number decreases by 4 and the atomic number by 2.- beta-minus radiation (emission of a beta- particle = an electron)Hence for the emitting nucleus the mass number remains the same and the atomic number increases by 1 (a neutron decays into a proton and beta- radiation)- beta-plus radiation (emission of a beta+ particle = a positron)Hence for the emitting nucleus the mass number remains the same and the atomic number decreases by 1 (under the addition of energy a proton decays into a neutron and a positron)- gamma radiation (emission of high energetic photons)The emitting nucleus doesn't change its mass number and atomic number,but it jumps from a higher energy level to a lower energy level.
Alpha particles have the greatest mass among nuclear emissions, as they consist of two protons and two neutrons. However, gamma rays have the most penetrating power, as they are highly energetic electromagnetic radiation that can penetrate through solids and tissues.
Alpha particles have the greatest mass of the three forms of nuclear radiation. They consist of two protons and two neutrons bound together, which gives them a relatively high mass compared to beta particles and gamma rays.
This process is known as gamma decay, which involves the emission of a gamma ray photon. Gamma rays are a form of electromagnetic radiation that carries energy but does not change the mass or nuclear charge of the atom. Gamma decay is typically associated with nuclear reactions and can occur after alpha or beta decay to stabilize the nucleus.
Alpha particles are a type of nuclear radiation with a mass of 4 atomic mass units. They consist of two protons and two neutrons bound together.
alpha - 2 neutrons and 2 protons released or neutron collision with a fissionable nucleus resulting in the fissioning of the atom into two fission fragments and more neutrons creating two atoms each a little less than half the atomic mass of the original atom
because of the force and radiation

Beta
True. Gamma ray emission involves the release of high-energy photons from the atomic nucleus without changing the mass or nuclear charge of the emitting atom.
