the mass of electrons is negligble the pe rcentage of an atom's mass comes from its 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.
The mass of an atom is primarily determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass since electrons have negligible mass. The exact mass of an atom can be found by adding up the masses of its protons, neutrons, and electrons.
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 mass of an atom is primarily concentrated in its nucleus, which is composed of protons and neutrons. Electrons, which have much less mass, orbit the nucleus in energy levels. The total mass of an atom is determined by the combined mass of its protons, neutrons, and electrons.

in the nucleus of an atom -proton and neutrons , electrons in the orbit has the negligible mass.
Approximately all of the atom's mass is in the nucleus. The electrons contribute almost zero.No atom has more than 100 electrons, but eachproton or neutron in the nucleushas the mass of more than 1,800 electrons.
The sum of masses of protons, neutrons and electrons.
The mass of an atom is determined by the sum of the masses of its protons, neutrons, and electrons. The protons and neutrons are located in the nucleus and contribute most of the mass, while the electrons, which have much less mass, orbit the nucleus. The mass of an atom is typically measured in atomic mass units (amu).
It is the nucleus. Mass of electrons is too small
Approximately all of the atom's mass is in the nucleus. The electrons contribute almost zero.No atom has more than 100 electrons, but eachproton or neutron in the nucleushas the mass of more than 1,800 electrons.
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.
Protons and neutrons make up most of the mass of an atom. Electrons weigh almost nothing by comparison.
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.
Protons and neutrons are the particles that account for most of an atom's mass. Electrons, which have much less mass, play a negligible role in the overall mass of an atom.
