The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
electrons
Electrons are negatively charged subatomic particles, but have almost no mass. The mass of an electron is about 1/2000 that of a proton or neutron. The neutron is the most massive of the subatomic particles at 1.6755 x 10-24 grams.
Positron
Proton or neutron
Electron
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
Yes, a neutron has mass. The mass of a neutron is slightly greater than the mass of a proton, which is another subatomic particle found in the nucleus of an atom. Neutrons and protons are both much more massive than electrons, which are the smallest subatomic particles.
This particle is the electron with a mass of 5,485 799 094 6(22)×10−4 amu.
among these Electron has the least mass....
In the atom the electron is the lightest.
These particles are protons and neutrons.
The largest subatomic particle (by mass) is the proton. The mass of subatomic particles is measured in atomic mass units (amu). The proton has a mass of 1.007 amu, the neutron has a mass of 1 amu, and the electron has a mass of .0005 amu.

electrons
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.
This particle is the electron: 9,10938291(40)×10−31 kg or 5,4857990946(22)×10−4 amu.
