This is a great video of the types of chemical reactions, and is easy to undestand because it has funny 3D elements and their formula at the bottom Steffano Solari

**__ Quarks __**
 * Quarks are the smallest subatomic particle discovered at the time. They are elementary particles that are involved in constitution of matter because they combine to form HADRONS that are a bound of quarks; examples of hadrons are protons and neutrons. Some of the properties of quarks are: electric charge, color charge, spin and mass. There are six types of quarks: **
 * 1) **** Up (u): is a quark of the first generation. It is the lightest of all quarks. **
 * 2) **** Down (d): is also from the first generation and is the second lightest quark. It is commonly founded in protons and neutrons. **
 * 3) **** Charm (c): is a second generation quark. Is the fourth most massive quark and is approximately one and a half times the mass of a proton. **
 * 4) **** Strange (s): second generation quark. Is the third lightest. **
 * 5) **** Top (t): third generation quark. Is the most massive of known elementary particles. **
 * 6) **** Bottom (b): third generation quark. It has the largest mass quark like 4 times the mass of a proton.

**__ Strong force __**
 * Quarks are hold together by the strong force or strong interaction. It is one of the 4 fundamental interactions: gravitation, electromagnetic force and weak interaction. It is called STRONG force because it is the most powerful of the four. It is mediated by gluons. The word gluon comes from the word GLUE so they make quarks interact. **

**__ Subatomic particles __**
 * The subatomic particles include: electrons, protons and neutrons. **** Protons and neutrons are composite particles and are formed by quarks. Protons are formed by two up quarks and one down quark, and the neutrons are formed by one up quark and two down quarks. Photons and neutrinos are other particles formed by the sun. Other subatomic particles are been discovered in x-rays. **
