From The American Heritage® Student Science Dictionary and The American Heritage® Children's Science Dictionary.

charge A property of all particles of matter that causes them to be attracted to or pushed away from other particles. Particles with the same charges drive each other away; particles with opposite charges draw each other together. Protons have a positive charge, and electrons have a negative charge.

Nature likes things to be electrically balanced or neutral, with equal amounts of positive and negative charges. To achieve this balance, atoms give up or take up electrons, the particles that have negative charge. This giving and taking of electrons is how chemical elements combine to make compounds.

electrode A piece of metal or carbon through which an electric current can enter or leave an electric device. Batteries have two electrodes, positive and negative.

electronics The science that deals with electrons and with devices and systems that operate by using electrons. Electronics has led to the development of radio, TV, flights in space, and computers.
