Oxygen Elements In A Chemical Reaction Between Priestley And Wilhelm

My project was about Oxygen , Oxygen was discovered in 1774 by Joseph Priestley and Carl Wilhelm. They both independently discovered oxygen, They were both able to produce oxygen by heating mercuric oxide (Hg0) . Oxygen is a highly reactive element and is capable of combining with other elements . It is required by most living organisms and for most forms of combustion . Oxygen and Magnesium combine in a chemical reaction to form this compound. When the magnesium metal burns it react with oxygen found in the air to form Magnesium Oxide. Mg loses the electrons to have an octet , Oxygen gains two electrons to have an octet ; The bond between ions results from the electrostatic attraction of opposite charges. The formula would be Mg0. The symbol

The Electrons per shell is 2,6 . One of the resources i used was www.rsc.org/periodic-table/element/8/oxygen . That website was telling me about how oxygen have many properties and the group number for oxygen is 16 the period is 2 and the state is at 20 C. The ChemSpider ID is 140526 and a ChemSpider is a free chemical structure database . The key isotopes is O16. Another website i used was www.livescience.com/28738-oxygen.html . The website tells you about Earth has been oxygenated for about 2.3 billion to 2.4 billion years, and levels began to creep up at least 2.5 billion years ago, according to a 2007 NASA-funded study. No one knows quite why this lung-friendly gas suddenly became a significant part of the atmosphere, but it's possible that geologic changes on Earth led to oxygen produced by photosynthesizing organisms sticking around, rather than being consumed in geologic reactions, according to the study researchers. Another resource i used was .On this website it tells you the different sources of https://education.jlab.org/itselemental/ele008.html oxygen and the ways it is used

Oxygen can also be combined with acetylene (C2H2) to produce an extremely hot flame used for welding. Liquid oxygen, when combined with liquid hydrogen, makes an excellent rocket fuel. Ozone (O3) forms a thin, protective layer around the earth that shields the surface from the sun's ultraviolet radiation. Oxygen is also a component of hundreds of thousands of organic compounds. For the last resource i used was the website https://www.britannica.com/science/oxygen At 46 percent of the mass, oxygen is the most plentiful element in Earth’s crust. The proportion of oxygen by volume in the atmosphere is 21 percent and by weight in seawater is 89 percent. In rocks, it is combined with metals and nonmetals in the form of oxides that are acidic (such as those of sulfur, carbon, aluminum, and phosphorus) or basic (such as those of calcium, magnesium, and iron) and as salt like compounds that may be regarded as formed from the acidic and basic oxides, as sulfates, carbonates, silicates, aluminates, and phosphates. Plentiful as they are, these solid compounds are not useful as sources of oxygen. Those four websites was the four resources I
