Facts about the Definition of the Element Oxygen A colorless tasteless odourless gaseous element that constitutes 21 percent of the atmosphere and is found in water, in most rocks and minerals, and in numerous organic compounds, that is capable of combining with all elements except the inert gases, that is active in physiological processes, and that is involved especially in combustion processes. The most common uses of Oxygen are in Oxidizer, Rocket propulsion, Medicine, Welding, Sensors, Mask and Concentrators
Interesting Facts about the Origin and Meaning of the element name Oxygen What are the origins of the word Oxygen ? The name originates from the Greek words gennan meaning 'generate' and oxus meaning 'acid' - so named because it was believed that all acids contained oxygen.
Facts about the Classification of the Element Oxygen Oxygen is classified as an element in the 'Non-metals' section which can be located in groups 14,15 and 16 of the Periodic Table. Non-metals are not easily able to conduct electricity or heat and do not reflect light . Non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. Non-metallic elements exist, at room temperature, in two of the three states of matter : gases (such as oxygen) and solids (such as carbon).
Brief Facts about the Discovery and History of the Element Oxygen Oxygen was discovered by Carl Wilhelm Scheele in Sweden in 1771 and then by Joseph Priestley in 1774. It was named by Antoine Laurent Lavoisier in 1774.
Occurrence of the element Oxygen in the Atmosphere Constitutes 21 percent of the atmosphere Found in water, in most rocks and minerals, and in numerous organic compounds Oxygen comprises about 87% by weight of the oceans as H2O - water
Common Uses of Oxygen Oxidizer Rocket propulsion Medicine Welding Oxygen sensors Oxygen mask Oxygen concentrator

Facts and Info about the element Oxygen - IUPAC and the Modern Standardised Periodic Table The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 which includes the Oxygen element. The famous Russian Scientist, Dimitri Mendeleev, perceived the correct classification method of "the periodic table" for the 65 elements which were known in his time. Oxygen was discovered by Carl Wilhelm Scheele in Sweden in 1771 and then by Joseph Priestley in 1774. It was named by Antoine Laurent Lavoisier in 1774. The Standardised Periodic Table now recognises more periods and elements than Dimitri Mendeleev knew in his day but still all fitting into his concept of the "Periodic Table" in which Oxygen is just one element that can be found.
