Electrons
Tiny particle moving around outside the nucleus of an atom. Each electron has one unit of negative charge (-) and almost no mass. (source: EPA) Background from Wikipedia For other uses, see Electron (disambiguation). The electron is a fundamental subatomic particle that carries an electric charge. It is a spin-½ lepton that participates in electromagnetic interactions, and its mass is less than one thousandth of that of the smallest atom. Its electric charge is defined by convention to be negative, with a value of -1 in atomic units. Together with atomic nuclei, electrons make up atoms; their interaction with adjacent nuclei is the main cause of chemical bonding.
