The three particles that make up an atom are protons, neutrons and electrons. Protons and neutrons both have a mass of 1 unit, whereas the mass of an electron is 1/1837 of that of a proton or a neutron. Therefore, the electron has the least mass as its mass is considered negligible.
The particle you are referring to is likely a proton. Protons are subatomic particles found in the nucleus of an atom and have a positive electrical charge. They also have mass, although their mass is much smaller than everyday objects.
A particle that has a large mass and a positive charge is known as an alpha particle. These particles contain 2 protons and 2 neutrons which are bound together to form an identical particle to a helium nucleus.
Neutron has neutral charge. It is present inside nucleus.
Protons and neutrons are subatomic particles that are responsible for most of an atom's mass. Protons have a positive charge, neutrons are neutral, and both are found in the nucleus of an atom. Electrons, which have a much smaller mass, orbit around the nucleus.
The mass of an atom is primarily determined by the protons and neutrons it contains since electrons have negligible mass. With 38 neutrons and an atomic number of 31 (which corresponds to the number of protons), this atom is likely a neutral atom of gallium. The approximate mass of this neutral atom can be calculated using the atomic mass of gallium (around 69.7 g/mol).
Which particle? The electron.
the electron
the electron
In the atom this particle is the electron. Generally in the particle physics: photons, gluons, neutrinos.
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
An electron has the least mass among the three fundamental particles of an atom, which includes protons and neutrons.
A proton is an elementary particle that is identical to the nucleus of a hydrogen atom. It carries a positive electric charge and accounts for the majority of the mass within an atom.
least - electron most - the top quark
The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or atomic mass units.
The Electron.
Mass of electron is not included for the calculation of mass of an atom.
The election within an atom would have the least mass. Protons and neutrons have a mass roughly that of 1amu, while an electron's is 1/1840 of an amu.
