    1. 1. Hayley Wayne
    2. 2. • Name of Element : Neon• Symbol of Element : Ne Neon• Atomic Number of Neon : 10• Atomic Mass:  20.1797 amu• Melting Point: -248.6 °C - 24.549994 °K• Boiling Point: -246.1 °C - 27.049994 °K• Number of Protons/Electrons in Neon : 10• Number of Neutrons in Neon : 10• Crystal Structure: Cubic• Density at 293 K: 0.901 g/cm3
    3. 3. Neon was discovered by Scottish Chemist Sir William Ramsay and his student Morris Travers in 1898 in London, England. Sir William Ramsay discovered the noble gases and received the Nobel Prize in Chemistry in 1904 in recognition of his services in the discovery of the inert gaseous elements in air. These elements included Argon, Krypton, and Xenon. Ramsay also isolatedHistory Helium. In 1910, Ramsay also made and characterized Radon.
    4. 4. Some Facts about• Neon• The name neon originates from Neon is the second lightest the Greek word neos meaning noble gas after Helium. new.• Neon is a rare inert gaseous element occurring in the atmosphere and obtained through fractional distillation of liquid air.• Neon costs approximately $33 per 100 grams.
    5. 5. Uses of Neon• Neon lights and signs. Neon lighting was invented by the french chemist Georges Claude. A neon light consists of a glass tube filled with neon. An electric current is passed through the tube which causes neon atoms to break apart. The part recombine almost immediately and the give off neon light.
    6. 6. More Uses for Neon • Neon and helium are used to make gas lasers. Neon is used in lightning arrestors, television tubes, high-voltage indicators, and wave meter tubes. Liquid neon is used as a cryogenic refrigerant, as it has over 40 times the refrigerating capacity per unit volume than liquid helium and over three times that of liquid hydrogen.
    7. 7. Abundances in Different Environments• % in Universe: 0.13%• % in Sun: 0.1%• % in Meteorites: N/A• % in Earths Crust: 3x10-⁷%• % in Oceans: 1.2x10-⁸• % in Humans: N/A
    8. 8. Isotopes of Neon• Neon has 3 stable isotopes Ne²⁰, Ne²¹, and Ne²². It also has 16 other isotopes that are unstable and radioactive.
