γ (gamma) is a photon.
A gamma wave...
The gamma ray is not a particle but is just an EM wave that transmits energy.
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.
Gamma.
Gamma radiation is the most energetic and penetrating of the options provided, followed by the alpha particle, beta particle, and antineutrino, in descending order.
Alpha Particle
No. There's a reason that a beta particle can only penetrate a couple of mm and that a gamma particle can go through everything.
The speed of a gamma particle is approximately the speed of light, which is around 299,792 kilometers per second in a vacuum.
When an iodine-131 atom decays by emitting a beta particle and a gamma particle, it forms xenon-131. The beta particle is an electron, while the gamma particle is a high-energy photon. This decay process helps iodine-131 become a stable element, xenon-131.

Gamma, as it has the most energy by far.
