Electricity is a form of energy. Electricity is the flow of
electrons. All matter is made up of atoms, and an atom has
a center, called a nucleus. The nucleus contains positively
charged particles called protons and uncharged particles
called neutrons. The nucleus of an atom is surrounded by
negatively charged particles called electrons. The negative
charge of an electron is equal to the positive charge of a
proton, and the number of electrons in an atom is usually
equal to the number of protons. When the balancing force
between protons and electrons is upset by an outside force,
an atom may gain or lose an electron. When electrons
are "lost" from an atom, the free movement of these
electrons constitutes an electric current.
