Almost all of the mass of an atom is in the nucleus. The nucleus is made up of protons and neutrons, with hydrogen-1 as the lone exception because its nucleus has only a proton in it. In other atoms, protons and neutrons are fused together to form that nucleus. The electrons are out in their electron cloud. And we mention the electron because it has only about 1/1836th the mass of a proton. See how it works? A fistful of electrons weigh almost nothing compared to a single proton. The neutron is slightly heavier than a proton, so when neutrons and protons are gathered in any atomic nucleus, it contains most all of the mass of that atom.

More than 99.99 % of the mass of an atom is concentrated in the nucleus and consists mainly of protons and neutrons.

The mass of an atom is focused in the nucleus at the center of an atom. The nucleus is suronded by electrons that orbit the dense center. Electrons, however, have very little mass.
Most of the mass of an atom is found in the nucleus which contains the protons and neutrons.
When calculating the mass of an atom, you add the mass of the protons and the neutrons. This is the nucleus of the atom. The electrons are small enough to be ignored except in the most delicate calculations.
An atom's mass is concentrated in its nucleus, which is located in the center of the atom. Protons and neutrons within the nucleus are responsible for its mass; the electrons, which are located outside of the nucleus, don't contribute to the mass of the atom.
most of the mass is contained in the nucleus.the mass is spread evenly through the whole atom, and the electron cloud.
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.
