Etymology[edit]
Borrowed from French oxygène (originally in the form principe oxygène, a variant of principe oxigine ‘acidifying principle’, suggested by Lavoisier), from Ancient Greek ὀξύς (oxús, “sharp”) + γένος (génos, “birth”), referring to oxygen's supposed role in the formation of acids.
Pronunciation[edit]
Noun[edit]
oxygen (countable and uncountable, plural oxygens)
- The chemical element (symbol O) with an atomic number of 8 and relative atomic mass of 15.9994. It is a colorless and odorless gas.
- Hypernym: chalcogen
- Molecular oxygen (O2), a colorless, odorless gas at room temperature, also called dioxygen.
- 2013 September-October, Katie L. Burke, “In the News”, in American Scientist:
- Oxygen levels on Earth skyrocketed 2.4 billion years ago, when cyanobacteria evolved photosynthesis: the ability to convert water and carbon dioxide into carbohydrates and waste oxygen using solar energy. The evolutionary precursor of photosynthesis is still under debate, and a new study sheds light.
- (medicine) A mixture of oxygen and other gases, administered to a patient to help them breathe.
- (countable) An atom of this element.
- 2013, Spencer L. Seager, Michael R. Slabaugh, Chemistry for Today: General, Organic, and Biochemistry, page 479:
- Look first at any structure to see if there is a carbon with two oxygens attached. Hemiacetals, hemiketals, acetals, and ketals are all alike in that regard.
- (figurative) A condition or environment in which something can thrive.
- Silence is the oxygen of shame.
- They hoped to starve the terrorists of the oxygen of publicity.
