In chemistry, an octatomic element is an element that, at some standard temperature and pressure, is in a configuration of eight atoms bound together (a homonuclear molecule). The canonical example is sulfur, S8, but red selenium is also an octatomic element stable at room temperature. Octaoxygen is also known, but it is extremely unstable.
