The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
In the atom the electron is the lightest.
In the atom this particle is the electron. Generally in the particle physics: photons, gluons, neutrinos.
The electron is the lightest particle in the atom.
The electron.
These particles are protons and neutrons.
Electrons have a mass of only about 0.0005 as much as protons or neutrons.
The lightest subatomic particle of an atom is the electron. It has a very small mass compared to protons and neutrons, making it a key component in determining the chemical properties of an atom.
Electron, lightest stable subatomic particle known. It carries a negative charge, which is considered the basic unit of electric charge. The rest mass of the electron is 9.109 × 10−31 kg, which is only 1/1,840the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom.
The subatomic particle with the greatest mass is the neutron. Neutrons are found in the nucleus of atoms along with protons, but they are slightly more massive than protons. Electrons, which orbit the nucleus, have much less mass compared to neutrons and protons.
6 subatomic particles. 2 protons and 2 neutrons (that accounts for the mass of 4 amu) as well as 2 electrons.
A neutron is a neutral subatomic particle found within the nucleus of an atom. It has no electric charge but contributes to the mass of the atom. Neutrons help stabilize the nucleus by balancing the repulsive forces between positively charged protons.
