ELECTROSTATIC

Electricity is a form of energy associated with phenomena caused by electric charges, whether they are moving (electrodynamic) or at rest (electrostatic). All matter is made up of molecules which, in turn, are formed by atoms. Atoms are formed by a nucleus, where protons and neutrons meet, and by an electrosphere, made up of orbits where electrons rotate. The basic difference between these three elements that make up the atom lies in their electric charges. While the neutron has a neutral charge, that is, it has no charge, the proton has a positive charge and the electron has a negative charge. Every atom is in principle electrically neutral since the number of protons is equal to the number of electrons, causing each positive charge to nullify a negative charge and vice versa.
