I believe that in gold atoms, 99.994% of the mass comes from its nucleus. Electrons way thousands times less than neutrons and protons, and since the protons/neutrons are nucleons the mass comes from the nucleus.

Where is most the mass of an atom called?

The majority of an atom's mass is found in its nucleus, which is located at the center of the atom. The nucleus is composed of protons and neutrons, which are much more massive than the electrons that orbit the nucleus.


Where is all the mass of an atom concentrated in?

The mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. The nucleus is extremely small compared to the overall size of the atom, but it contains almost all of the atom's mass. Electrons, which are much smaller in mass, orbit around the nucleus.


An atom has no mass?

An atom does have mass. The mass of an atom is primarily concentrated in its nucleus, which is made up of protons and neutrons. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.


What parts of an atom makes up all the mass of an atom?

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.


Where is the mass of an atom concetrated?

The mass of an atom is concentrated in the nucleus, which is the center of the atom. The nucleus contains protons and neutrons, which account for most of the atom's mass. Electrons, which are much smaller in mass, orbit around the nucleus in energy levels.


Why do the mass of atom depend upon the nucleus?

The mass of an atom depends on the nucleus because the nucleus contains the majority of the atom's mass in the form of protons and neutrons. Electrons, which orbit the nucleus, have a much smaller mass compared to protons and neutrons. The mass of an atom is essentially the combined mass of its protons and neutrons in the nucleus.


The mass of an atom is contained primarily in its?

The mass of an atom is primarily contained in its nucleus, which is made up of protons and neutrons. Electrons, which have a much smaller mass compared to protons and neutrons, occupy the space surrounding the nucleus.


The majority of the atom's mass is found in the?

The majority of an atom's mass is found in the nucleus, which contains protons and neutrons. Electrons, which are much smaller in mass, are located in the electron cloud outside the nucleus.


In the atom nearly all the mass is found in the what?

An atom is comprised of protons, neutrons, and electrons. The electrons take up the most space as they orbit the nucleus. But nearly all of the mass of the atom is found in the nucleus of the protons and neutrons.


Where is most of the atoms mass found?

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.


What part of the atom is the heaviest has the most mass?

The nucleus of an atom is the heaviest part and contains most of the atom's mass. It is made up of protons and neutrons. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.


Where is the great majority of the mass of the atom found?

The great majority of the mass of an atom is found in the nucleus, where protons and neutrons are located. The nucleus is incredibly dense and accounts for almost all of the atom's mass, while electrons, which are much smaller and lighter, contribute very little to the overall mass of the atom.
