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 up and down quarks which form the protons and neutrons make up most of the mass of the atom, along with the binding energy that holds them together. Remember that energy is mass and mass is energy, per Einstein's mass-energy equivalence equation e=mc2.
The atoms volume is made up of the space in which the electrons move.
Protons and neutrons make up most of the mass of an atom.
The nucleus.
An electron weighs about 1/1836 of a proton, so as far as an atom is concerned, all the mass is in the nucleus, with the protons and neutrons. But the electrons are rotating in their orbits a long way (in proton size terms) from the nucleus. So most of the volume of an atom is empty space.
the electron
True, most of an atom's volume is the space in which electrons move.
most of an atoms volume is nothing, think of the atom as a football stadium, a football in the centre is the neucleus, electrons would be the size of peas in the very back row, the rest is empty space. on top of that the neclues is made of protons and neutrons, which spaces between, these necleons are made of quarks which also have empty space between them, the quarks are made of neons which again have spaces between. Many physicists believes this continues in this fashion.
the electron cloud. some people say that's its mostly made up of "nothing" , but that is incorrect. it has to have SOMETHING in it or else it wouldn't be an atom, no? and yes i have done research on this, so i know that my answer is 100% accurate.
Empty space makes up most of the volume of an atom. The nucleus (protons and neutrons) make up most of the mass.
These particles are proton and neutron.
Most of the mass is in the nucleus; most of the volume is in the electron "cloud".
Most of the volume of an atom is vacuum.

An atom.
An electron weighs about 1/1836 of a proton, so as far as an atom is concerned, all the mass is in the nucleus, with the protons and neutrons. But the electrons are rotating in their orbits a long way (in proton size terms) from the nucleus. So most of the volume of an atom is empty space.
Protons believe me
Most of the volume in an atom is occupied by the electron cloud. Most of the complex reactions of the atom occur in the cloud.
the electron
It would be neutrons.
No. An electron as a particle is small however the probability cloud of an electron can be large- most of the volume of an atom consists of the electron cloud. In relation to this the nucleus, although it contains nearly all of the mass of the atom, is quite small.
