During school we’ve learned about atoms and their use in life, be it for good or as weapons of mass destruction. And what about the history of the discovery of the atom itself, I am sure there are many people who do not know, here’s his review:

The development of atomic structure was donated by many scientists. Chronology of the atomic structure revealed the discovery of atomic particles and their arrangement in the atom.

Atoms are the building blocks of all matter. An atom consists of three particles – neutrons (no charge), protons (positively charged) and electrons (negatively charged). The number of protons present in the atom is called the atomic number, while the mass of the atom is the number of protons plus the average number of neutrons. Each different elements found in nature differ in the number of third-atomic particles. In general, atomic number used to define an element, for example, an element with atomic number 8 is oxygen and vice versa. An element has a fixed number of protons, but can have varying numbers of neutrons. Atoms with different numbers of neutrons are called as isotopes.
