protons and neutrons make up most of the mass in an atom
Empty space makes up most of the volume of an atom. The nucleus (protons and neutrons) make up most of the mass.
The nucleus makes up most of the mass and the other things in the atom make up the rest.
The nucleus is the part of an atom that contains practically all its mass. In the nucleus, you can find the proton and neutron. The number of electrons, which move about the nucleus, is equal to the number of protons.

The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
That is called the nucleus. It is positively charged and it makes up most of the atom's mass.
These particles are proton and neutron.
The nucleolus.
The mass of the nucleus makes up most all of the mass of an atom. The only things outside the nucleus are the electrons. The mass of an electron is ~9.11E-31 kg. The mass of an electron is 1/1836 that of a proton.
Most of the size of an atom is made up of the electron cloud, where electrons are located. The nucleus, which contains protons and neutrons, is much smaller in comparison to the overall size of the atom.
