The electron is one of the tiny particles that make up an atom (or subatomic particles) together with protons and neutrals. The electrons are always outside the nucleus of the atom composed of a combination of protons and neutrons. To show how small the electron is, we can say that its mass is 1/1836 times that of the proton. The name of electron comes from the idea that, thanks to their negative energy, they generate electricity on the nucleus of the atom.
The electron could only be isolated and understood in the mid-nineteenth century when scientists understood that there was a negative force in the atom that was attracted to the nucleus. This situation allowed us to understand that the electricity generated in an atom is the result of the attractive and repulsive force that protons and electrons exert on themselves.
Electrons are particles that fall within the group of leptons, that is, those that are subject to the electromagnetic force, the gravitational force, etc. Of all the particles known as leptons, the electron is the one that has been most understood in its nature, having a stable quality. Furthermore, along with protons and neutrons, the electron is also considered a fundamental particle since it cannot be divided into units smaller than itself.
The discovery, analysis and understanding of the electron has undoubtedly been relevant to human life since this has allowed the discovery of electricity, a vital element for today's lifestyle. Along with this, thousands of elements and devices that base their structure on electronics have been developed over time in order to allow human beings to better understand what surrounds them and to obtain higher levels of quality of life. .
