The Standard Model of the Atom
The atomic model seen to the left is a detailed version of the now standard atomic model. Initially thought to be fundamental bits of matter, it is now known that atoms are made up of protons, neutrons, and electrons. Then, further research showed that protons and neutrons were made up of even smaller particles called quarks.
In an atom, there are two fundamental categories of matter: quarks and leptons.
To go along with these there are also present antiquarks and antileptons, whose presence will be further explained later in this section.
Atoms are held together with force carrier particles, such as gravity.
The mass of atoms is measured in atomic mass units. The atomic mass unit is the standard benchmark with which to measure the mass of any atom. It is approximately 1/12 the mass of a carbon-12 atom.
