Name and symbol of [|element]: Oxygen and O Boiling point: -182.95 degree C Melting point: -218.79 degree C Specific Gravity/Density: 1495 kg Atomic mass: 16g Atomic number: 8 Electron configuration and orbital notation: 1s2 2s2 2p4, How,when,where discovered: Oxygen was discovered by Joseph Priestley in 1774 in Wiltshire. England. But also by C.W. Scheele in Sweden. A gas that enhanced combustion was found when Scheele heated many compounds together such as potassium,nitrate,manganese oxide, and mercury oxide. Where and how produced, processed, or mined: found in the sun,involved in carbon-nitrogen cycle Chemical and physical properties: colorless,odorless and tasteless diatomic gas. Dissolves better in cold water then hot. Minerals, compounds, or ores in which found: 3rd most abundant element found in sun. Two common chemical reactions: air, water Industrial or commercial uses: used very much in steel industry
