Physics has not managed to discover a particle that accounts for mass
The two particles in the nucleus [protons and neutrons] account for almost all of the mass in an atom.
Almost the entire mass of an atom is in the center of an atom. The respective particles are protons and neutrons. Electron's mass is relatively negligible.
These particles are the proton and the neutron.

the electron particles make up the mostr mass
It is usually considered to be neutrons and protons that hold most of an atom's mass, however there is one theoretical subatomic particle that is used to help explain mass, called the higgs boson particle.
The charge of the proton is positive while the charge of the electron is negative. This keeps the atom together. Unlike most atoms, the hydrogen atoms have only two particles in them.
These particles are the protons and neutrons.
Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus, with a very small contribution from the orbiting electrons
The up and down quark accounts for most of an atoms mass. Two up quarks and one down quark forms a proton, and one up quark and two down quarks forms a neutron. Protons and neutrons form the nuclei of atoms, and comprise most of their mass, along with the binding energy holding them all together.
The proton and the neutron make up most of the mass of a hydrogen-2 atom.
Protons and neutrons have near identical mass. One will not have to account for the difference in mass in most calculations.
These particle are neutrons and protons; they are located in the atomic nucleus.
Neutrons is the answer. Both protons and neutrons have almost equal mass and concentrated in nucleus. Electrons have negligible mass as compared to mass of protons and neutrons and such minor figures are discarded in physics as much as mass isconcerned. Mass of electron is 1/1836 as compared to proton. But electric charge wise 'both' are equal and apposite.
