Answer:
alpha particle, proton, beta particle
Explanation:
Protons are fundamental sub-atomic particles present inside the nucleus of an atom. The mass of a proton is around 1 amu (atomic mass unit).
Alpha (α) and beta (β) particles are by products of radioactive decay. Alpha particles are essentially a composite of 2 protons and 2 neutrons similar to the He nucleus. Therefore, the have a mass of 4 amu
Beta particles are high energy particles which can either be electrons (negative charge) or positron (positive charge). They have a mass which is 1/2000th the mass of a proton.
Therefore, the mass from the largest to the smallest would be:
alpha > proton > beta
