Elementary particles

Elementary particles refer to particles that cannot be easily recognized as a compound - in contrast to the nuclei of atoms. Within certain limits determined by the conservation rates, elementary particles can be converted.

Properties of some elementary particles

The multitude of such "elementary particles" - in addition to those listed in the table, a further 200 were found - led to the "invention" and eventually to the discovery of the "quarks" and subsequently to today's "standard model" of elementary particles. This standard model consists of twelve parts - see figure - and the same number of antiparticles. Thus, the proton consists of two "up-quarks" and one "down-quark", the neutron of one "up" and two "downs", where the up-quark has a charge of -2/3 and the down-quark +1/3 electric elementary charges to meet the electric charge conditions.
