What is the electron
Electron - the lightest electrically charged particle, which is involved in virtually all electrical phenomena. It is thanks to its low weight, most involved in the development of quantum mechanics. These fast particles are widely used in the field of modern science and technology.
Word ἤλεκτρον - Greek. That gave it the name of an electron. It translates it as "amber". In ancient times, Greek natural scientists conducted various experiments which consisted of rubbing hair amber pieces, which then began to attract various small items. Electron named negatively charged particle, which is one of the basic units that make up the structure of matter. The electronic shells of atoms are composed of electrons, and their position and number are determined by the chemical properties of veschestva.O number of electrons in the atoms of different substances can be found in the table of chemical elements, composed DI Mendeleev. The number of protons in the nucleus of the atom is always equal to the number of electrons to be in the electron shell of the atom of the substance. Electrons revolve around the nucleus at a tremendous speed, and so they do not "fall" into the nucleus. This is clearly comparable to the Moon, which does not fall, despite the fact that the Earth is its prityagivaet.Sovremennye representation of particle physics suggest structurelessness and indivisibility of the electron. The movement of these particles in semiconductors and metals allows easy transfer and manipulate energy. This feature is widely used in electronics, home, industry, information technology and communications. Despite the fact that the conductors of the velocity of the electrons is very small, the electric field can propagate with the speed of light. This current through the entire circuit is set momentalno.Elektrony, in addition to corpuscular have also wave properties. They participate in gravitational, weak and electromagnetic interactions. Electronic stability follows from the laws of conservation of energy and conservation of charge. This particle - the lightest of the charged, and therefore can not be everything to decay. The disintegration into particles lighter is prohibited by the law of conservation of charge, and the decay to heavier than the electron particles forbidden by the law of conservation of energy. On the accuracy with which made the law of conservation of charge, can be judged from the fact that the electron, at least ten years, a charge does not lose.
