### Elementary Particles Snapshot

This section includes tutorials which explain a relatively young branch of modern physics, elementary particles. Besides the three known elementary particles (proton, neutron and electron), there is a large number of other particles, most of them have a very short life. The chapter begins with some useful background information covering quantum numbers and atomic orbitals, the meaning of which is used to explain the meaning of elementary particles and antiparticles. Later, the concept of electron-positron pair, which eventually brings pair annihilation, is explained. The first guide ends with the explanation of Yukawa Theory - a theory that tries to explain the behavior of elementary particles.

The second guide includes information about the particle-antiparticle interaction and properties. In addition, this tutorial deals with the laws of conservation, which are also applied at this microscopic level of matter existence, as well as other features of elementary particles such as strangeness, baryon and lepton charge.

The section ends with the classification of elementary particles according to various criteria, as well as the various types of interaction. In addition, more advanced concepts such as quarks, charm, standard model, etc., are all explained in this tutorial.

### Elementary Particles Calculators

In addition to the Elementary Particles tutorials, we also provide online Elementary Particles Calculators which allow you to calculate specific Elementary Particles formula in support of the tutorials or to check and verify your own calculations in support of your homework, coursework or thesis.

The following Physics Calculators are provided in support of the Elementary Particles tutorials.
