Mass
Boson
- WP: Vector_boson - a boson with the spin quantum number equal to 1
- WP: Photons - carry the electromagnetic interaction
- WP: W_and_Z_bosons - carry the weak interaction
- WP: Gluon - strong interaction
Atomic
- WP: Atomic_physics - deals with the atom as a system consisting of a nucleus and electrons
- WP: Atom - a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons.
- WP: Atomic_nucleus - contains a mix of positively charged protons and electrically neutral neutrons (except in the case of hydrogen-1, which is the only stable nuclide with no neutrons)
- WP: Nucleon
- WP: Atomic_number - the number of protons found in the nucleus of an atom and therefore identical to the charge number of the nucleus
