Oxygen By: Cody Newcomb
General Info. • I have an atomic number of 8; atomic weight of 15.9994; period number of 2; group number 16; and in the Chalcogen group. • Melting point of 54.36K (-218.79⁰C or -316.82⁰F) • Boiling point of 90.20K (-182.95⁰C or -297.31⁰F)
Info. Continued…. • Density of 0.001429 grams per cubic centimeter. • I am considered to be in the Gas phase. • Classified as a non-metal. • I was founded by Joseph Priestly and Carl Wilhelm, Priestly was given credit for the discovery.
Continued…. • They both produced me by heating mercuric acid (HgO). • I am the third most abundant element in the universe. • I am also highly reactive and is capable of combining with most other elements.
Continued….. • I have an oxidation state of -2 • I have 3 stable isotopes. • My electron configuration is 1s² 2s² 2p⁴. • I am a component of hundreds of thousands of organic compounds. • I make up the Earths atmosphere by nearly 21%.

What makes me so special? • I make life possible on Earth. • I was one of the first elements on earth. • I am a fundamental part of everyone’s life.
My best friends…. • I get along with almost every element except the noble gases, but my best friends are Sulfur(S), Phosphorous(P), Nitrogen(N), Carbon(C), and Hydrogen(H)….
The important things I have done… • I support life on Earth. • The trioxygen form of me prevents UV rays from entering the atmosphere. • I can dissolve in water making aquatic animals able to live.
Important Compounds that I make.. • When I form bonds with another element to make a binary compound, I am called oxide. • When I combine with sodium, I become sodium oxide. • The most important element that I bond with is Hydrogen, I then make H₂O (water). I am by far the most abundant compound of the oxides.
Physical and Chemical features… • Physical: I am a gas, I cannot be smelled, I am colorless, I am also a tasteless diatomic gas with the molecular formula of O₂. • Chemical: Molecular Dioxygen is needed for cellular respiration, Concentrated O₂ can be used for combustion, Oxygen is not a fuel source but the oxidant is.
