Is oxygen a molecule?

Posted December 13, 2022


Yes, oxygen occurs naturally in the atmosphere as a molecule. Oxygen molecules are made up of only one element – oxygen. Two oxygen atoms bind together with a covalent double bond to form an oxygen molecule (O2), also known as dioxygen. This type of molecule that is made up of two atoms of the same type is called a diatomic molecule.
