Oxygen is the third most abundant element in the universe and the most common element in the earth's crust (two thirds of the mass of the human body and nine tenths of the mass of water). and makes up about 20% of the air we breathe. Large amounts of oxygen can be extracted from liquefied air through a process known as fractional distillation.
