The alpha particle is much more massive than a beta particle. A beta particle is an electron, which has very little mass. An alpha particle is a helium nucleus, and consists of two protons and two neutrons.
The correct order is c) Alpha particle, beta particle, gamma ray. Alpha particles have the greatest mass, followed by beta particles, and then gamma rays which have no mass.
The alpha, beta, and gamma particles have different masses. An alpha particle has a mass of about 4 atomic mass units (u), which is roughly 6.64 x 10^-27 kg. A beta particle (electron or positron) has a much smaller mass, about 0.0005 u or 9.31 x 10^-31 kg. A gamma particle, which is a high-energy photon, has zero rest mass because it is pure energy.
Alpha decay means that an alpha particle (helium-4 nucleus) is emitted.Alpha decay means that an alpha particle (helium-4 nucleus) is emitted.Alpha decay means that an alpha particle (helium-4 nucleus) is emitted.Alpha decay means that an alpha particle (helium-4 nucleus) is emitted.
They are Alkali metals, Alkaline Earth metals, and Carbon 16. ----
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.
Alpha Particle
From Physics Forums The alpha particle has a 2+ charge, beta has 1- charge, and the gamma is neutral (no charge). The beta particle could also have a 1+ charge if it undergoes positron emission [a proton turns into a neutron and a positron (the "anti-electron")]
Gamma.
The correct order is c) Alpha particle, beta particle, gamma ray. Alpha particles have the greatest mass, followed by beta particles, and then gamma rays which have no mass.
Beta decay is a non-example of alpha decay. Beta decay involves the emission of a beta particle (either an electron or a positron) from an unstable atomic nucleus, whereas alpha decay involves the emission of an alpha particle (helium nucleus) from a nucleus.
The alpha, beta, and gamma particles have different masses. An alpha particle has a mass of about 4 atomic mass units (u), which is roughly 6.64 x 10^-27 kg. A beta particle (electron or positron) has a much smaller mass, about 0.0005 u or 9.31 x 10^-31 kg. A gamma particle, which is a high-energy photon, has zero rest mass because it is pure energy.

Gamma radiation is the most energetic and penetrating of the options provided, followed by the alpha particle, beta particle, and antineutrino, in descending order.
Gamma
Alpha particles are the same size as a helium nucleus and are made up of 2 protons and two neutrons. They have no electrons so an alpha particle has a +2 charge
The gamma ray is not a particle but is just an EM wave that transmits energy.
