Respuesta :
Two oxygen atoms strongly bind together with a covalent double bond to form dioxygen or O2.
Chemical elements, or substances with only one sort of atom, include oxygen. An oxygen atom has eight protons in its nucleus, as indicated by its atomic number of 8 and the official chemical symbol O. At room. temperature, oxygen. is a gas that. is tasteless, odorless, and. colorless. The molecule of oxygen is present in nature. Dioxygen, or O2, is created when a covalent double bond firmly binds two oxygen atoms together. Another pure oxygen variant is ozone. In the stratosphere of the Earth, it develops. O2 molecules are disassembled into lone oxygen atoms by ultraviolet radiation (UV). The lone oxygen atoms join O2 molecules to create O3 (the chemical formula for ozone). O3 concentrations are greater in the stratosphere because there is more UV.
