How a small number of atoms can be joined and form completely different substances.Video Are you having trouble understanding the basics of atomic elements? This video will walk you through: Want to learn more details and data about Oxygen (O)? Check my Elements Comprehensive List. Small amounts are made in the laboratory by electrolysis of water or heating potassium chlorate (KClO3) with manganese dioxide (MnO2) catalyst.ĭiscoveryDiscovered By: Joseph Priestly, Carl Wilhelm Scheele SourcesObtained primarily from liquid air by fractional distillation. ![]() Name OriginGreek: oxys and genes, (acid former). Naturally occuring ozone (O3) in the upper atmosphere shields the earth from ultraviolet radiation. UsesUsed in steel making, welding, and supporting life. It is the most abundant element in the earth's crust, and makes up almost 21% of the atmosphere. Third most abundant element in the universe. In the case of Oxygen the valence electrons is 2. Now let's check the facts about Oxygen.ĭescriptionColorless, odorless, tasteless gas pale blue liquid. Ok but how many valence electrons does an atom of Oxygen have? A valence electron is an outer shell electron and may participate in the formation of a chemical bond.
