General Info:
  • Element name: Oxygen
  • Element symbol: O
  • Atomic number: 8
  • Atomic mass: 15.9994
Atomic Structure:
  • Number of protons within the nucleus: 8
  • Number of electrons within the neutral atom: 8
  • Most common Isotope: Oxygen-16
  • Number of neutrons within the nucleus of the most common isotope: 8
Background:
  • The Discovery of Oxygen
    • First discovered by a swedish chemist Carl Wilhelm Scheele in 1772
    • Antoine Lavoisier, a French chemist also discovered oxygen in 1775, and was the first to recognize it as an element.
    • Origin of Name: Lavoisier named it "oxygen" which comes from a Greek word that means "acid-former".
  • Common uses
    1. The most common use of oxygen is respiration.
    2. Also used in medal production especially steel (Bessemer Process)
Physical Properties:
  • State of matter at room temperature: gas
  • Melting Point: -218.8°C
  • Boiling Point: -183°C
  • Density: 1.429 g/cm given at O at 0° celsius
  • Abundance in Earth's crust: 46%
Chemical Properties:
  • Other elements that react with Oxygen: All elements have some known compliments with Oxygen except for Krypton, Argon and Helium.
  • Compounds that contain Oxygen: There are many compounds that contain Oxygen. The Two most common are Carbon Dioxide and Water.
  • The most important use of oxygen is breathing. Breathing is the process which moves air in and out of the lungs. Oxygen is needed by all living organsms(Aerobic organisms) because they require oxygen in order to release energy through respiration.Without oxygen, cells will not be able to carry out aerobic respiration. Through the process of aerobic respiration food is converted into energy and this allows all human and animals to perform daily activities and survive. Without oxygen humans and animals will not be able to survive.
