Oxygen is a colorless and odorless gas, the most common elemental form of oxygen. Insoluble in water, 1L of water dissolves about 30mL oxygen. Oxygen in the air accounts for about 21%, liquid oxygen is sky blue, solid oxygen is blue crystal. At room temperature is not very active, and many substances are not easy to act. But at high temperature, it is very active, and can directly combine with a variety of elements, which is related to the electronegativity of oxygen atoms after fluorine.
