Oxygen - it's everywhere! Joradn Ferdman - Leone c


Oxygen, classified as a nonmetal on the periodic table, is a colorless, odorless, and tasteless gas. The word oxygen (O) originates from Greek words "oxys" and "geinomai" meaning to bring forth acid. It was originally, but incorrectly, thought by early scientists that oxygen was needed to form all acids. Oxygen itself was discovered in 1774 by Joseph Priestley by a series of experiments. Priestley proved the presence of oxygen by several different experiments with an upside down container, such as heating the air with flame then putting a plant inside of the heated jar.

The atomic number of oxygen is is 8.

The atomic mass of oxygen is 16.

Oxygen has has 8 protons, 8 neutrons and 8 electrons.

Oxygen has 3 different stable isotopes: O-16, O-17, and O-18



One of the main natural sources of oxygen is plants undergoing photosynthesis. Oxygen is also the third most abundant element found in the sun. Additionally, oxygen is part of the carbon-nitrogen cycle, the cycle once thought to give the sun and stars their energy. (http://periodic.lanl.gov/8.shtml)

One of the major uses of oxygen is, as shown in the photo above, steel making. Oxygen is vital to the production of steel because of how highly reactant it is; in an experiment shown in the Discovery video, a stream of pure oxygen is directed at a piece of burning charcoal which immediately begins to spark. The large amount of oxygen helps support the combustion of the charcoal, but the oxygen itself does not actually burn as oxygen is inflammable.

Oxygen is, as we all know, very important because we need it to breathe. Oxygen can also help people with respiratory issues because certain machines provide the sick with more oxygen. Finally, oxygen is used for water purification.

Science Fact: As a gas, oxygen is clear. But as a liquid, it's pale blue. Also, oxygen has six valence electrons making it highly reactant. (http://www.livescience.com/28738-oxygen.html)
