  • Element name: Neon
  • Element symbol: Ne
  • Atomic Number: 10
  • (Not rounded) Atomic Mass: 20.1797
Atomic Structure
  • Number of protons in the nucleus: 10
  • Number of electrons in the nucleus: 10
  • Most common isotope: Ne-20
  • number of neutrons in most common isotope: Ne-20 contains 10 neutrons
  • scientists who discovered or made the element were Morris Travers and William Ramsay
    • They found this element through the study of liquefied air
  • It was discovered in the year 1898
  • The name Neon is from the Greek word νέον which means "new"
  • It is most commonly used for advertising signs and is used to make high voltage indicator. It is also combined with helium to make helium-neon lasers
Physical Properties
  • At room temperature neon is in the state of a gas
    • Melting point (in °C): 258.59°C
    • Boiling Point (in °C): -246.08°C
    • Density: 0.0008999 grams/cubic centimeter
  • Abundance at earths crust: 3x10-7 %
Chemical properties
  • Neon doesn't tend to react with other elements because it is a noble gas and it already has a stable electron configuration
  • There are no compounds that contain neon since it is a noble gas and it is for the most part nonreactive
  • The most important use of neon is using the lights in making advertising signs. Sign making accounts for its largest use and by using neon lighting in a sign it is sure to capture someones attention. This light produces an unmistakable bright reddish-orange light. Although still referred to as "neon", other colors are generated with different noble gases or by varied colors of fluorescent lighting. This can benefit many companies by drawing attention to what they are trying to advertise.

  • Neon is a colorless, odorless inert (not chemically reactive) gas
  • Neon is the fifth most abundant chemical element in the universe after hydrogen, helium, oxygen, and carbon.
  • It is a rare gas in Earth's atmosphere, making up just 0.0018%.
  • If you could gather all the neon from the rooms in a typical new home in the United States, you would get 10 liters (2 gallons) of neon gas.
