In the atom the electron is the lightest.
All subatomic particles have mass.
The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
Subatomic particles have mass, dimensions, spin, sometimes have an electrical charge.
neutrons and protons
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
These particles are the protons and neutrons.
The neutron is the subatomic particle that has appreciable mass and lacks a charge.
Subatomic particles are the same size as basketballs.
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.
These particles are protons and neutrons.
Protons and neutrons
They have a mass and are components of the atom.
