3 days ago · Oxygen is a chemical compound with symbol O and atomic number 8. In the periodic table, it is the member of the chalcogen group, an extremely reactive nonmetal, and an oxidizing agent that readily produces oxides with most elements as well as with other elements.
There are two key methods used to obtain oxygen gas. The first is by the distillation of liquid air. The second is to pass clean, dry air through a zeolite that absorbs nitrogen and leaves oxygen. A newer method, which gives oxygen of a higher purity, is to pass air over a partially permeable ceramic membrane.
