An alpha particle is identical to B, a helium nucleus. Specifically, it consists of two protons and two neutrons, making it the same as the nucleus of a helium-4 atom.
In beta particle emission, a neutron in the nucleus converts into a proton, an electron (beta particle), and an antineutrino.
Neutron
energy
When tritium-3 emits a beta particle, it becomes helium-3. The beta particle is an electron, so when it is emitted, a neutron in the tritium nucleus is converted into a proton, resulting in helium-3, which has two protons and one neutron.
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
hydrgen nucleus
neutron, but only in the isotope H-1 (protium)
The pair form a hydrogen atom.There is a fallacy that's taught about this pairing, which is that the electron-proton pair form a neutron. See my answer to the question "What particle has the same mass as a hydrogen atom?" for more details about this, and why it is wrong.

This particle is the neutron.
Electron!
Hydrogen usually has no neutrons. However, there is also the heavy hydrogen, a.k.a. deuterium, that has both a proton and a neutron in its nucleus.
Neutron
Yes. The electron is the smallest whole particle.
The isotope hydrogen-1 don't contain neutrons.
among these Electron has the least mass....
Ion.
