If you think to the boson Higgs this is not a small particle.
subatomic particle
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
a subatomic particle
The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
Quark is the smallest particle ever discovered.
Excluding all subatomic particles, theElectron
In the atom the electron is the lightest.
Of the three basic particles that atoms are made of, the electron is the smallest.
among these Electron has the least mass....
electrons the smallest but weigh as much as protons neutrons weigh nothing ~Kay
A colloid is not a subatomic particle.
This particle is the electron with a mass of 5,485 799 094 6(22)×10−4 amu.
