What is the Meaning of: Electron | Concept and Definition of: Electron

Meanings, definitions, concepts of daily use
Means electron the lightest elementary particle constituting the atoms and that presents the least possible load of negative electricity. It is a subatomic particle that surrounds the nucleus of the atom, and is composed of protons and neutrons.
Electrons are the attractions between atoms and generate, through the movement, the power on most metals. They were discovered by the British physicist Joseph John Thomson (1856-1906), although its existence has been suggested by the physicist George Johnstone Stoney (1826-1911).
The mass of the electron is 1,800 times smaller than the mass of the proton. Even if electrons are part of atoms, there are electrons which form beams in vacuum or that move independently by the material. If the electrons move out of the atom, they can generate electric current.
The static load, on the other hand, occurs when a body atoms have more or less electrons than those which are necessary to balance the positive charge of their core. If the atom unless electrons, the body is loaded positively; If less, the charge is negative.
The movement of electrons allows that we have electricity in our homes. Tube televisions that emit cathode rays are also based on an electron beam that is deflected by a magnetic field prior to project on the fluorescent screen. Semiconductors, electron microscopes, transistors and welders also use electrons.
