Octatomic element
Molecule composed of eight atoms of the same element
From Wikipedia, the free encyclopedia
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,[1] but red selenium is also an octatomic element stable at room temperature. Octaoxygen is also known, but it is extremely unstable.
