P2+-+Noble+Gasses

Our element, Noble Gasses are Helium, Neon, Argon, Krypton, Xenon, and Radon. Theses elements are gasses. Most these elemnets were discovered by Sir William Ramsay in different time periods. Helium was discovered in 1895, and Neon was discovered in 1898. Argon was dicovered in 1894, Krypton in 1898, Xenon in 1898, and Radon was discovered by Fredrich Ernst Dorn in 1898. All of the noble gases are monatomic, which means they made up of one atom. These atoms all boil at low temperatures, Helium boiling the lowest.



Three physical properties are that they all freeze at low temperatures, they are inert, meaning they don't strengthen or move and they are monatomic. Three different chemical properties of noble gases are they are odorless, they don't react with other elements and when they are electrically charged they glow inside of glass tubes.



Some interesting facts about neon; one of the noble gases is that it is "Neo" means new in greek, and that neon is manufactured. Another interesting facts is that the reason the noble gases are inert, meaning unable to move or have strength, is because their outer shell of electrons is full so they have an oxidation number (oxidation, meaning to be chemically combined with oxygen) of 0.



One use of helium, a noble gas is that it's low density and inertness made it a great gas to use for light air crafts such as balloons. Another use for neon, another noble gas is that it is well known for its signs, and any glass tube can be filled with neon. These are two common uses of the gases helium and neon.
