Definitions for oxygen
ˈɒk sɪ dʒənoxy·gen

oxygen, O, atomic number 8(noun)
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

Oxygen(n.)
(Chem.) A colorless, tasteless, odorless, gaseous element of atomic number 8, 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 15.9994.
Etymology: [F. oxygne, from Gr. 'oxy`s sharp, acid + root of gi`gnesqai to be born. So called because originally supposed to be an essential part of every acid.]

oxygen(Noun)
A chemical element (symbol O) with an atomic number of 8 and relative atomic mass of 15.9994.
Etymology: Borrowed from oxygène (originally in the form principe oxygène, a variant of principe oxigine ‘acidifying principle’, suggested by Lavoisier), from ὀξύς + γένος, referring to oxygen's role in the formation of acids.
oxygen(Noun)
Molecular oxygen (O), a colorless, odorless gas at room temperature.

oxygen(Noun)
A mixture of oxygen and other gases, administered to a patient to help him or her to breathe.

Oxygen
Oxygen is a chemical element with symbol O and atomic number 8. Its name derives from the Greek roots ὀξύς and -γόνος, because at the time of naming, it was mistakenly thought that all acids required oxygen in their composition. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula O2. This substance is an important part of the atmosphere, and is necessary to sustain most terrestrial life. Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element that readily forms compounds with most elements except the noble gases Helium and Neon. Oxygen is a strong oxidizing agent and only fluorine has greater electronegativity. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium and the most abundant element by mass in the Earth's crust, making up almost half of the crust's mass. Oxygen is too chemically reactive to remain a free element in Earth's atmosphere without being continuously replenished by the photosynthetic action of living organisms, which use the energy of sunlight to produce elemental oxygen from water. Free elemental O2 only began to accumulate in the atmosphere about 2.5 billion years ago about a billion years after the first appearance of these organisms. Diatomic oxygen gas constitutes 20.8% of the volume of air.

Oxygen
oks′i-jen, n. a gas without taste, colour, or smell, forming part of the air, water, &c., and supporting life and combustion.—n. Oxychlō′ride, a chemical compound containing both chlorine and oxygen in combination with some other element.—v.t. Ox′ygenāte, to unite, or cause to unite, with oxygen.—n. Oxygenā′tion, act of oxygenating.—v.t. Ox′ygenise (same as Oxygenate).—adj. Oxyg′enous, pertaining to, or obtained from, oxygen.—adj. Oxyhy′drogen, pertaining to a mixture of oxygen and hydrogen, as in a form of blowpipe in which jets of either ignite as they issue from separate reservoirs. [Gr. oxys, sharp, gen, the root of gennaein, to generate.]

Oxygen
a colourless, inodorous gas which constitutes one-fifth in volume of the atmosphere, and which, in combination with hydrogen, forms water. It is the most widely diffused of all the elementary bodies, and an essential support to everything possessed of life.

Oxygen
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.

E. D. Hirsch, Jr.:
We have ignored cultural literacy in thinking about education ... We ignore the air we breathe until it is thin or foul. Cultural literacy is the oxygen of social intercourse.
Richard Levitan:
Their X-ray's looked awful, their oxygen was terrible, and yet they're completely awake, alert on a cell phone, and they all said is they've been somewhat sick for days, and then only recently did they notice either shortness of breath or fatigue or something else.
Lisa De Jesús:
They were not numbers, they were people, and the government thinks that just putting a Band-Aid on things, it's all OK. But, no. What about our feelings? What about those people who died trying to put Puerto Rico back (together) again? People needed (electricity) because they had oxygen (machines). They were ill, they had cancer. They had other issues, health-wise. They needed the government, and the government failed them.
Barbara Bush:
When I was born in Midland, Texas, my little eyes opened and there I was, probably crying and trying to get a little oxygen, i looked up, and Barbara Bush was there. I didn't know it at the time, but I won the lottery.
