Definitions of oxygen

  1. a nonmetallic bivalent element that is normally a colorless odorless tasteless nonflammable diatomic gas; constitutes 21 percent of the atmosphere by volume; the most abundant element in the earth's crust
  2. A colorless, tasteless, odorless, gaseous element occurring in the free state in the atmosphere, of which it forms about 23 per cent by weight and about 21 per cent by volume, being slightly heavier than nitrogen. Symbol O. Atomic weight 15. 96.
  3. Chlorine used in bleaching.
  4. An element with atomic symbol O, atomic number 8, and atomic weight 16. It is the most abundant element on earth and essential for respiration.
  5. A colorless, odorless, tasteless gas, which forms one- fifth by volume of the atmosphere.
  6. Oxygenium ( U. S.), a gaseous element, symbol O, atomic weight 16, the most abundant and widely distributed of all the chemical elements; it combines with most of the other elements to form oxides, and is essential to animal and plant life. Oxygen is employed by inhalation in pneumonia, in dyspnea and cyanosis, and is sometimes given to athletes before a contest with the idea that it increases the " wind" and the staying powers.
