the mass of electrons is negligble the pe rcentage of an atom's mass comes from its protons and neutrons
What else can I help you with?
Where is most of the mass of an atom contained?
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.
What is the mass of an atom found by?
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.
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.
How the mass of an atom is organized?
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.
What particle in the atom is the least massive?
least - electron most - the top quark
Where is most of the mass of an atom contained?

Where is most of the mass of an atom contain?
in the nucleus of an atom -proton and neutrons , electrons in the orbit has the negligible mass.
What is the mass of an atom found by?
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.
Where is almost all of the mass in an atom is located?
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.
What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.
What is determined the mass of an atom?
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).
Where in the atom is the mass of the atom concentrated?
It is the nucleus. Mass of electrons is too small
Where is the most of the atoms mass located?
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.
What particles take up most of the mass of an atom?
Protons and neutrons make up most of the mass of an atom. Electrons weigh almost nothing by comparison.
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.
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.
Which particles account for most of an atoms mass?
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.
