How can Xenon and Krypton form compounds with Fluorine if they are inert gases?

Answer 1

Because #"inert gas"# is a misnomer.

The #"Noble Gases"# have a full valence electron shell, and they rarely form compounds with other elements.
However, with highly reactive elements, and fluorine and oxygen are the most reactive elements, a few of the #"Noble Gases"# can form isolable compounds, since their valence orbitals stick out far enough from the nucleus to allow sufficient reactivity.

Answer 2

Even though xenon and krypton are inert gases, they can react chemically with fluorine under certain circumstances, especially when exposed to highly reactive elements like fluorine. In these compounds, xenon and krypton usually act as oxidizing agents, which enables them to bond with fluorine and form stable compounds like krypton difluoride (KrF2) and xenon hexafluoride (XeF6).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
