Noble gas 稀有气体

（重定向自Rare gas）

The noble gases make a group of chemical elements with similar properties. Under standard conditions, they are all odorless, colorless, monatomic gases with 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). Ununoctium (Uuo), which was recognised as an element in December 2015, is predicted to be a noble gas as well but this fact is not confirmed.
