The fundamental particles, Physics

The fundamental particles:

Although other atomic particles are known, the three fundamental ones are:

Protons. The proton has unit mass and carries a unit positive charge.

Neutron. The neutron has unit mass but no electrical charge.

Electron. The electron has only 1/1836 unit of mass but it carries a unit negative charge.

Thus, although we have 92 types of naturally occurring atoms, they are all built-up from different numbers of these three fundamental particles.

Thus our picture of the structure of matter is as shown below.
