Noble gas

High Quality Content by WIKIPEDIA articles! The noble gases (often mistakenly referred to as inert gases) are a group of chemical elements with very similar properties: under standard conditions, they are all odorless, colorless, monatomic gases, with a very low chemical reactivity. The six noble gases that occur naturally are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).For the first six periods of the periodic table, the noble gases are exactly the members of group 18 of the periodic table. However, this no longer holds in the seventh period (due to relativistic effects): The next member of group 18, ununoctium, is probably not a noble gas. Instead, group 14 member ununquadium exhibits noble-gas-like properties.
