Browsing: Oxygen
Oxygen is a chemical element with the symbol O and atomic number 8. It is a highly reactive non-metal and an oxidizing agent that readily forms oxides with most elements and compounds. Oxygen is vital for life on Earth; it is a key component of cellular respiration for most terrestrial life forms and a critical component of the Earth’s atmosphere, making up approximately 21% by volume. In the atmosphere, oxygen mainly exists as diatomic molecules (O2), but it also occurs as the triatomic molecule ozone (O3), which plays a crucial role in protecting Earth from harmful ultraviolet radiation. Beyond biological processes, oxygen is used in various industrial applications, including steelmaking, welding, and as a propellant in rocketry. Its ability to support combustion makes it essential in energy production and medical settings, where it supports breathing in clinical treatments.
