Noble gas noble gases show extremely low chemical reactivity; consequently, only a few hundred noble gas compounds have been formed. Neutral compounds in which helium and neon are involved in chemical bonds have not been formed (although there is some theoretical evidence for a few helium compounds), while xenon, krypton, and argon have shown only minor reactivity. The reactivity follows the order Ne < He < Ar < Kr < Xe < Rn. In 1933, Linus Pauling predicted that the heavier noble gases could form compounds with fluorine and oxygen. He predicted the existence of krypton hexafluoride () and xenon hexafluoride (),

Love Is the Sweetest Thing "Love Is the Sweetest Thing" is a popular song written in 1932 by British band leader and singer Ray Noble. Using guest vocalist Al Bowlly, Noble's recording was a big hit on both sides of the Atlantic, bringing Noble his first American success. It was published by Redwood Music.
