Oxygen, as a scientific topic, encompasses the study of the element with atomic number 8, its diatomic molecular form (O₂), and its reactive allotropes and species (e.g., O₃, reactive oxygen species). Research addresses its physicochemical properties, electronic structure, and behavior in gaseous, liquid, and solid phases, as well as its central role in redox reactions, combustion, and bioenergetics. The topic also includes oxygen transport and utilization in biological systems, oxygen cycles in environmental and Earth system science, and its involvement in oxidative stress, signaling pathways, and industrial processes such as oxidation catalysis and materials processing.
