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.

CH4 is Methane. The first(smallest) alkane, which is a functional group of hydrocarbons.
The covalent compound name for SeF2 is selenium difluoride.
XeO3 is Xenon trioxide. NB ; The heavier Noble(Inert) gases, like Xenon, can be 'forced to react' under certain conditions.
The covalent compound name for SCl2 is sulfur dichloride.
F2 is fluorine, which is an element, not a compound.
No, Al2O3 (aluminum oxide) is an ionic compound, not a covalent compound. It is made up of Al3+ and O2- ions held together by ionic bonds.
The name of the covalent compound SeF is selenium (IV) fluoride.
