What is solid oxygen?

Solid oxygen is a crystalline form of oxygen that exists at very low temperatures, typically below -218 degrees Celsius. It is most commonly found in laboratories and in natural occurrences in the atmosphere, such as during the freezing of liquid oxygen.

Solid oxygen has a pale blue color and a molecular structure that is similar to that of ozone. It is a nonmetal with a melting point of -218.4 degrees Celsius and a boiling point of -183 degrees Celsius.

Solid oxygen is extremely reactive and can form compounds with other elements, such as carbon and hydrogen. It is used in various applications in chemistry and physics, such as in the study of superconductivity and as a powerful oxidizing agent in chemical reactions.

Overall, solid oxygen has limited practical applications due to its extreme reactivity and low stability at room temperature.
