    Oxygen was discovered for the first time by a Swedish Chemist, Carl Wilhelm Scheele, in 1772. Joseph Priestly, an English chemist, independently, discovered oxygen in 1774 and published his findings the same year, three years before Scheele published. Antonie Lavoisier, a French chemist, also discovered oxygen in 1775, was the first to recognize it as an element, and coined its name "oxygen" - which comes from a Greek word that means “acid-former”.

    There is a historic dispute about who discovered oxygen. Most credit Priestly alone or Both Priestly and Scheele.

    Properties of Oxygen:-Oxygen gas is colorless, odorless, and tasteless. The liquid and solid forms are a pale blue color and are strongly paramagnetic. Oxygen supports combustion, combines with most elements, and is a component of hundreds of thousands of organic compounds. Ozone (O3), a highly active compound with a name derived from the Greek word for 'I smell', is formed by the action of an electrical discharge or ultraviolet light on oxygen.

    Uses of oxygen:- 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 most abundant element found in the sun and the earth, and it plays a part in the carbon-nitrogen cycle. Excited oxygen yields the bright red and yellow-green colors of the Aurora. Oxygen enrichment of steel blast furnaces accounts for the greatest use of the gas. Large quantities are used in making synthesis gas for ammonia, methanol, and ethylene oxide. It is also used as a bleach, for oxidizing oils, for oxy-acetylene welding, and for determining carbon content of steel and organic compounds. Plants and animals require oxygen for respiration. Hospitals frequently prescribe oxygen for patients. Approximately two thirds of the human body and nine tenths of the mass of water is oxygen.

    It is related to biology as well as chemistry in biology it is related because the human body needs oxygen for respiration. They need oxygen for some function in the human body. Therefore oxygen is related to biology

    Element 8 - oxygen was first ever (by credit) isolated by Joseph Priestley by thermally decomposing red mercuric oxide (cinnabar) in a test tube sealed with mercury (test tube upside down, creates vacuum cinnabar in vacuum). The only problem was he thought it was dephlogisticated air (phlogiston was thought to be the flammable component of any molecule). A french man called Lavoisier worked out what it actually was and called it oxygen so took most the fame. A swedish man called Scheele was actually the first man to do the experiment but his work was not published till it was too late for him to be credited with the discovery.

    Joseph Priestly discovered it in 1774 but did not realize it was called oxygen he called it dephlogisticated air instead. Antoine Lavoisier name it later. The rest of your information can be found here.

    Some are pretty easy, right? Who asks scavenger hunt questions? 1-Cobalt, Co 2-Chlorine, Cl 3-Tungsten,W 4-Platinum,Pt 5-(are you sure?) 6-Radon, Rn 7-Iodine, I 8-Calcium, Ca 9-Argon, Ar 10-Magnesium, Mg Find the rest on your own.

    In addition to Joseph Priestly, who heated HgO to get Hg + O2, Carl Willem Scheele discovered it independently by heating KNO3 to get KNO2 + O2.

    Darn, I just saw that a few weeks ago. Some British scientist who put a mouse in a bell jar and waited for it to suffocate.

    Don't worry, he revived the mouse afterwards.
