Where is most of the mass located in the helium atom?
Most of the mass in a helium atom is located in its nucleus, which contains two protons and usually two neutrons,forming a total of four particles called nucleons. The electrons only contribute a small fraction of the atom's overall mass.
What particles make up the mass of the atom?
Protons and neutrons, the particles that make up atomic nuclei, are the ones responsible for almost all of the mass of an atom. As the electron has less than 1/1800th the mass of a proton, a whole flock of electrons won't significantly change the mass of an atom. We look to the protons and neutrons (called nucleons when they are being considered as components of an atomic nucleus) to contribute to the mass of an atom, and they will be considered when we derive the atom weight of an element.
What contributes to the mass of the atom?
number of protons and number of neutrons
What Particles responsible for the mass of atom?
The three main sub-atomic particles of an atom are proton, neutron and electron. The mass of a proton is about 1800 times the mass of an electron and the masses of proton and neutron are almost similar. Hence, mass of only proton and neutron is counted towards the mass of an atom.
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass

What atomic particles carry mass?
Protons, neutrons, and electrons are atomic particles that carry mass. Protons and neutrons contribute most of the mass to an atom's nucleus, while electrons have a much smaller mass compared to protons and neutrons.
What subatomic particle contributes alomst no weight to an atom?
The subatomic particles that contribute most almost no weight to an atom are electrons at various energy levels. Isotopes of the same element differ from each other only by the number of neutrons.
What subatomic particles contribute to the mass of?
The atomic mass is the sum of the number of protons and the number of neutrons found in each atom of that element (electrons do not contribute). They are sometimes seen on periodic tables to have a decimal in the atomic number, this is for elements with more than one common isotope (an isotope of an element is the same number of protons but with a different number of neutrons), in which case an average of the common isotopes can be used.
What subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
What subatomic partices contribute to the mass of volume?
Electrons, due to their movement around the nucleus.

What particles make up most of the mass atom?
air,mater
What part of the atom contains most of its mass?
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
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.
What contributes to the mass of the atom?
number of protons and number of neutrons
What particles have the most mass?
In the atom the heaviest particle is the neutron but the proton is close.
