Oxygen  - One of the six molecules that dominate life. Oxygen is nice but greedy -electronegative. Oxygen is one of the six basic chemicals of life.  Six chemicals - carbon (C), hydrogen (H), oxygen (O),  nitrogen (N), sulfur (S) and phosphorus (P) - make up about 98 percent of the weight of people and trees.  Without oxygen, normal respiration does not take place.
