What are the electrons?

A s-electron a particle subatomics of negative load. It can free (not be connected to an atom, or be conexionado to the nucleus of an atom. The electrons in atoms exist in spherical armors of several radii, representing the energy levels. At the most great they are these spherical armors, greater will be the energy than it contains the electron.

In the electrical conductors, the current flows are resulting of the movements of atom electrons to atom individually, and of the negative poles to the positives generally. In the semiconducting materials, the current happens by the movement of electrons, but in some cases, he is more illustrative to see the current like a movement of deficiencies of the atom electron atom. An atom with deficiencies in a semiconductor is called hollow. These hollows move generally of positive the electrical poles to the negatives.

To put it another way, the s-electrons the particles smaller than they are within atoms. The atoms consist of protons (loaded positively), neutrons (without load) and electrons (loaded negative). You can imagine atoms as if they were a planet where it has some meteorites around orbiting to his. The planet represents the nucleus which consists of protons and neutrons, and the meteors orbiting are the electrons. These electrons move at a high speed around the nucleus.

Nevertheless, the electrons do not escape to the influence of the nucleus because they are tied by forces maintain that them in a continuous orbit.
