neutrons, followed by protons.
neutron
Negatively charged sub-atomic particle: electron. Positively charged sub-atomic particle: proton. Neutrally charged sub-atomic particle: neutron.
This is the neutron.
The electron is the sub-atomic particle that orbits the nucleus of an atom of matter. For anti-matter the sub-atomic particle that orbits the nucleus is the anti-electron (positron).
The sub-atomic particle that orbits the nucleus in an atom is called an electron.
Mass of electron is not included for the calculation of mass of an atom.
These particles are proton and neutron.
An atom is the smallest bit of matter that isn't a sub-atomic particle. Minerals are made of atoms.
The atomic number is the number of protons in an atom. If an atom is not ionized, the number of electrons must be the same as the number of protons.
sub-atomic would indicate that it would be found inside an atom.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
Of course it is smaller. It is a sub atomic particle
