Transcript of Neon

History of Neon Neon was discovered by Sir William Ramnsey and by Morris Travers.
This element was discovered in London, England in 1898, shortly discovered after the element Krypton.
Discovered through the study of liquefied
Obtained by liquefaction of air, then it is separated by fractional distillation. Atomic # Uses of Element Atomic structure and facts Molar mass . Melting Point - Boiling point - °C Although neon is the fourth most abundant element in the universe, only 0.0018% of the earth's atmosphere is neon.
Neon is the second-lightest noble gas.
Neon does not form any compounds since its a Noble gas. . . °C Density of gas - . Cryogenics
Scientists use neon in something called cryogenics. Cryogenics is when scientists freeze things very quickly. When neon gets very cold it becomes a liquid. Because neon is very non-reactive it is a good liquid to use TV Tubes

Next time you're watching television, you'll know that neon is one of the elements inside your TV tube.



Neon Signs
3 common isotopes of neon are
Ne-20Stable
Ne-21Stable
Ne-22Stable
All atomic numbers between 16 and 34 can be an isotope of neon.
There is always the same number of protons in each isotope. Atomic radius: 38 pm

ionic radii: 1+ ion , 3+ ion, 1- ion Ions: charge is neutral and common form is a a gas. Nonmetal 1st ionization energy:2080.6 kJ mol-1 https://www.webelements.com/neon/
