Before entering fully to define the word electron, it is very important that we establish its etymological origin. Specifically, we can establish that it comes from the Greek term elektron which meant "amber".
It is known as electron to the lightest essential particle that makes up a atom and that it presents the lowest possible charge in relation to negative electricity. It is a subatomic element that is located around the nucleus of the atom, formed by neutrons and protons .
Electrons are responsible for establishing the attractions between atoms and produce, through their movement, electric current in most metals. They were warned by the British physicist Joseph John Thomson (1856 -1906 ), although its existence had already been postulated by the scientist George Johnstone Stoney (1826 -1911 ).
The latter, an Irish-born physicist and mathematician born in Oakley Park in 1826, is considered to be the person who coined the term electron. In addition to this fact he has gone down in history for being one of the most important scientists thanks to his work on the structure of matter and the number of Avogadro that earned him the prestigious Nobel Prize.
The mass of the electron is about one thousand eight hundred times smaller than the mass of the proton. Although electrons are usually part of atoms, there are electrons that form you do in a vacuum or that they move independently by matter. If electrons travel outside the atom, they can generate electricity.
The static charge , instead, arises when the atoms of a body They have a smaller or larger amount of electrons than is needed to balance the positive charges of their nucleus. If the atom has fewer electrons, the body has a positive charge; If you have less, the charge will be negative.
The movement of electrons allows us to have electric current In our homes. Tube televisions that emit cathode rays are, on the other hand, based on an electron beam that is redirected by a magnetic field until the fluorescent screen is reached. Semiconductors, electron microscopes, transistors and welding machines also use electrons.
Although the concept we are addressing seems to us that it is only a fundamental pillar of science, we must be clear that it is not so because it is a basic part of our day to day. And it is that precisely, as we have mentioned, thanks to electrons we have, for example, the possibility of enjoying television.
Specifically, these essential particles are one of the central axes around which the cathode ray tube rotates, which is the one in the television that is responsible for proceeding, through magnetic fields, to impact the fluorescent screen that gives us the images of the news , movie or series that we are watching.
In relation to the aforementioned television, we have to mention that the term in question obtained a leading role in a children's program of the small screen that was broadcast in the 80s and 90s in Spain. It was "The Crystal Ball" where characters called electroduendes, who were experts in electronics, entertained the little ones with their "cathodic" adventures.
