On this page I'll provide comprehensive data for Oxygen. I hope you profit from it.
Oxygen Overview
Name Origin
Greek: oxys and genes, (acid former).
Symbol
O (Oxygen)Description
Colorless, odorless, tasteless gas; pale blue liquid. Third most abundant element in the universe. It is the most abundant element in the earth's crust, and makes up almost 21% of the atmosphere.
Discovery
Discovered By: Joseph Priestly, Carl Wilhelm Scheele
Year: 1774
Location: England/Sweden
Sources
Obtained primarily from liquid air by fractional distillation. Small amounts are made in the laboratory by electrolysis of water or heating potassium chlorate (KClO3) with manganese dioxide (MnO2) catalyst.
Uses
Used in steel making, welding, and supporting life. Naturally occuring ozone (O3) in the upper atmosphere shields the earth from ultraviolet radiation.
