Chemistry 20

October 14th, 2009


  • Chemical Symbol: Ne

  • Atomic Number: 10

  • Neon was discovered by two British chemists named Sir William Ramsay and Morris W. Travers

  • Neon was discovered when Ramsay took a sample of atmosphere, chilled it until it became a liquid, then heated it back up again and captured the gases as they boiled off. This resulted in three gases being released: Krypton, Xenon and Neon. (Wikipedia 2)

Physical properties
Physical Properties

  • Melting point: -249 degrees Celsius

  • Boiling point: -246 degrees Celsius

  • Colorless, odourless and tasteless noble gas

  • Density: 0.9 g/L

  • State at Room Temperature: Gas

  • Average Atomic Mass: 20.1797amu

Chemical properties
Chemical Properties

  • Heat of Fusion: .3317kJ/mol

  • Neon is an inert gas, and tends to not react with anything like many of the other noble gases. This is because it contains equal electrons, and therefore doesn’t want to react with anything

  • When electricity is passed through this gas, the electrons get excited and produce a reddish-orange color. This is why Neon and other noble gases are used in the sign industry.

Where in the world
Where in the World?

  • Neon is the 4th most abundant element in the Universe

  • Found in Earth’s atmosphere as a gas, and exists in single neon atoms

  • Makes up about .0018% of the volume of Earth’s atmosphere, or 1 part per 65,000


  • Neon is used in the sign industry because it reacts with electricity inside a glass tube causing the tube to light up with a reddish-orange color.

  • Liquid Neon is an economical coolant. It’s cooling capacity is three times that of liquid nitrogen. Also, Neon is inert, compact and inexpensive.

  • Used in the making of high-voltage indicators

  • Both Helium and Neon are used in gas lasers
