Uses:Oxygen was the atomic weight standard of comparison for the other elements until 1961 when the International Union of Pure and Applied Chemistry adopted carbon 12 as the new basis. It is the third mostabundant elementfound in the sun and the earth, and it plays a part in the carbon-n...

Oxygen is element number 8 on the periodic table of elements. Molecular oxygen, or oxygen gas, has the formula O_2_ and is therefore diatomic (has two atoms). It can exist as a liquid at extremely low temperatures. Oxygen makes up about 21 percent of the gas in the atmosphere. Fortuito...
The oxygen element is present in the periodic table with the chemical symbol O. It is one of the most important elements on Earth. In fact, without oxygen, most life would not be able to survive. Today, it makes up about 21% of the atmosphere, but the planet was very different 2.4 ...
Oxygen is the first element in Group 16 (VIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The elements in Group 16 are said to belong to the chalcogen family. Other elements in this group include sulfur, selenium, tellu...
Element No. 8 on thePeriodic Table of the Elementsis a colorless gas that makes up 21 percent of Earth's atmosphere. Because it's all around, oxygen is easy to dismiss as dull and inert; in fact, it's the most reactive of the non-metallic elements. ...
Oxygen, of course! Oxygen is the eighthelementon the periodic table of elements, where it's represented by the letter O. An element is the simplest form of matter there is--it can't be broken down into any simpler parts. Chemists call the air that we breathe O2 because there are two...
Oxygen (pronunciation: OK-si-jen) is a colorless element that belongs to the group of Chalcogens inthe periodic table, and it is represented by the chemical symbol O[1, 2, 3]. A highly reactive non-metal, it can easily form oxides with most of the other elements and their compounds[3...
