Octatomic element

In chemistry, an octatomic element is a 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,[1] but red selenium is also an octatomic element stable at room temperature. Octaoxygen is also known, but it is extremely unstable.
