The atomic number for Neon is 10, keeping in mind that the atomic number is the number of protons in an element. The atomic mass of Neon is 20.180, which when rounded up will become an atomic mass of 20. The state of matter Neon is mainly in is a gaseous state. The full electron configuration of neon is 1s2 2s2 2p6, and the abbreviated electron configuration is [He] 2s2 2p6. The melting point of Neon is at -248.59 degrees Celsius, and the boiling point is at -246.046 degrees Celsius. Neon has a density of 0.0008999 grams per cubic centimeter ("Facts About Neon." LiveScience. TechMedia Network). The stable isotopes of Neon are Neon-20 with a percent abundance of 90.48%, Neon-21 with a percent abundance of 0.27%, and Neon-22 with a percent abundance of 9.25%. Neon also has 16 other isotopes, but they are either unstable or they are radioactive. The neon gas can be found in small amounts in earth's …show more content…
Neon has no color (colorless), and it has no smell (odorless). Neon will not react with another substance. Neon is known not to be toxic and is used largely to create illuminated signs for advertisements. Bright signs that are red contain only pure Neon. The chemistry behind how neon lights work is when the atoms of the inert gas, is present in a glass tube, and when electrodes are attached to the tube and emit energy; it starts to light up ("How to Do Neon Lights Work?" Scientific American. Nap., 18 Feb. 2002). Some of the main reasons that Neon signs light up is due to when the gas has an electrical charge then the ions and the electrons start to collide and bounce around causing a red light to appear. There are more uses for Neon like making high voltage signs, and lasers. This element (liquid Neon) is also a cryogenic refrigerant and is used to freeze and keep things fresh. The fifth most abundant element in the universe is Neon. You can separate Neon out of the liquid air by fraction distillation. When distillation neon out of the liquid air, you will get some parts of Helium and parts of
