elcectron
Virtually all of the mass of an atom is carried by the proton and the neutron. The electron has very, very little mass relative to these two particles.
The largest subatomic particle (by mass) is the proton. The mass of subatomic particles is measured in atomic mass units (amu). The proton has a mass of 1.007 amu, the neutron has a mass of 1 amu, and the electron has a mass of .0005 amu.
a tiny subatomic particle related to the electron that has no electric charge and little mass is neutrino
When a beta particle is released, the atom's mass remains approximately the same because it loses an electron, which has such a small mass in comparison to the whole atom that it is negligible.
Basically nucleus is present in the centre of an atom which occupies very little space but it is responsible for most of the mass of atom. Its size can be assumed almost of a cricket ball IF atom is assumed as the stadium. being so small it still has a very complicated structure. It mainly contains 2 fundamental particles neutron - having no charge and mass=1.67493 x 10-27kg and proton having mass=1.67262 x 10-27kg and charge= +1.

These particles are protons and neutrons.
The electron is the lightest particle in the atom.
In the atom the heaviest particle is the neutron but the proton is close.

Physics has not managed to discover a particle that accounts for mass
It is called the nucleus and has a mass unit number of one.
A proton is a positively charged particle in the center of an atom. A neutron is another particle in the center of an atom that has no charge, but still has mass. Each particle, sometimes called a subatomic particle, has a mass of one AMU. The sum of these is the mass of one atom of an element. Electrons, the particles orbiting the nucleus, where protons and neutrons reside, are not taken into account in massing because they are so small.
The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or atomic mass units.
Which particle? The electron.
Mass is an intrinsic property of matter, it is not 'formed' by scientists. Mass is solidified energy as Einstein describes E=MC2 The Higgs particle is supposed to impart mass to matter.
