**Basic information of noble gases**
The noble gases also known as the inert gases are Group 18 on the periodic table and include Kryton, Neon, Argon, Xenon, and Radon. These elements are very stable and some of the less reactive elements due to a outer shell with 8 electrons.The noble gases are non-metal and are gases in there natural state.All of the elements in this family have interesting properties such as they are oderless,colorless, and have a low boiling point.

Krypton is one of the noble gases. It was discovered in 1895 by William Ramsay and Moris Travers. The word krypton comes from the greek word Kryptos meaning "hidden one" It's atomic number is 36 and has an atomic mass of 83.8. The melting point is -157.2 ºC or -250.96 ºF and a boiling point of -153.4 ºC or -244.12 ºF. Like all of the noble gases, Krypton has 8 valence electrons and rarely will react with any other element. IT is also colorless and odorless and is a white crystaline substance as a solid, but Krypton is a gas in its natrual state. However, it still has many uses.

Krytpon is used in energy effiecent lightbulbs and other lighting equipment such as lamps and flashlights. It can also be used for laser measurement and fills spaces in between double pane windows



.

**Neon**(Spenser Harms) Neon came from the Greek word //νέον// (//neon//) meaning "new one." Neon was discovered by Englishmen Sir William Ramsay and Morris Traver. They discovered in 1898. The atomic number of Neon is 10n and its atomic mass is 20.17. It has a melting point of -248.57°C and a boiling point of -246.0°C. It has a valence electron number of 8. Neon is very rare on earth ,but is found in abundance in the universe. It is found with other noble gases in neon signs and television tubes, and in helium-neon lasers. Some facts are:  Helium was named after the Greek god Helios the sun god. Discovered by Janssen in 1868 helium has an atomic mass of 4.0026. The melting point is -272.5 Celsius and the boiling point is -277.216 Celsius and has a valance number of 8. It is located in ores of uranium, radium, and other elements. Helium is used in welding, filling balloons, and liquid fuel for rockets. Some interesting facts are they use helium in MRIs, it cools nuclear reactors, helps create an artificial air source for divers, it is completely colorless, has the lowest melting point of the noble gases, and can become a solid by adding pressure.
 * Liquid Neon is 55 times more expensive than liquid helium
 * Least Reactive of the Noble Gases
 * Neon tubes are actually called Neon discharge tubes
 * First Neon discharge tube made by german glassblower Heinrich Geissler
 * French engineer Georges Claude is considered the inventor of the Neon sign
 * It takes 88,000 lbs of air to make one pound of Neon
