It's oxygen
This is the usual formula for elemental oxygen in its gaseous state. It could also be called a "diatomic oxygen molecule."
O2 is a covalent compound known as dioxygen, consisting of two oxygen atoms bonded together by a double covalent bond. It is a colorless, odorless gas that makes up approximately 21% of Earth's atmosphere.
The systematic name of this compound is Oxygen(II) Fluoride. N.B. This compound is a fluoride of oxygen. It should not be mistaken as a oxide of fluorine.
The covalent compound name for SeF2 is selenium difluoride.
The covalent compound name for SCl2 is sulfur dichloride.
