Atom. Computer artwork representing the structure of an atom. Three electrons are seen orbiting the central nucleus. The electrons each have a negative charge, which is balanced by positively- charged protons in the nucleus. The nucleus also contains neutral neutrons. This is a schematic "Bohr model" of an atom; electrons are thought to inhabit clouds of probability around a nucleus rather than fixed paths such as these.
