To understand that electricity is first necessary to know the atomic structure. Atom is the smallest part in an item that can be divided without losing its physical and chemical characteristics.
Atoms consist of positively charged particles (protons), neutral (neutrons) forming the core and these negatively charged the (electrons) orbiting the nucleus. We can imagine an atom as a solar system where the sun would be the nucleus that contains protons and neutrons and electrons orbiting planets would be orbiting around the nucleus.
Since electrons are negatively charged, remains on their orbits due to attraction of positively charged nucleus. But atoms are in different orbits, also called energy bands. It is in the final orbit (farthest from the nucleus) where electrons are less attracted to the nucleus and another atom can escape to close, leaving a free hole is quickly filled by an electron from another atom nearby, and so on , this is called conduction band.

When an atom is excited using, light, heat, etc., One of its electrons can absorb energy, jump to the conduction band and move from one molecule to another within a body pruduced a flow of electrons called electricity.

conductivity. It is the property of the atoms of the metals allows electrons revolving in its last orbit or conduction band move through their molecular structure conducting heat or electricity. According to the degree of conductivity that has a body, are classified into three groups:
conductors, insulators or dielectrics and semiconductors

Drivers. They are all metals lead to a greater or lesser extent, electricity and heat because the atoms tend to give up electrons easily turn in their final orbit. Gold (Au), the Silver (Ag), copper (Cu), aluminum (Al), tin (Sn) and platinum (Pt) are good conductors, while iron (Fe) and lead (Pb), for instance, are less so.

insulation or dielectric. Are materials in which electrons revolve in the last orbit of the molecules are strongly attracted to the core. This prevents you from moving freely through the molecular structure to which they belong, so do not drive or heat, or electricity. Among the good insulating materials are mica, Teflon, porcelain, plastics, etc. The air is also considered a good insulator heat and electricity.

Semiconductors. As its name implies, these materials are not exactly good conductors of electricity, but when they are excited electrons can move to the conduction band and to facilitate the electronic flow, but always in one direction. Hence the name "semiconductor."

Among semiconductor components or materials used by industry to make electronic devices such as diodes, transistors, integrated circuits and microprocessors are the silicon (Si), germanium (Ge) and gallium arsenide (GaAs).
