Are inert gases joined in pairs to form diatomic molecules?

Answer 1

The answer is no.................

Inert gases are discrete, atomic particles. Their molecules exist as individual atoms of the inert gas, with no interaction between them. Of course this so-called #"molecularity"# of the inert gases relates to the electronic structure of the atoms, in which the valence shell of the gas is completely filled.

Thus, inert gases, such as argon, neon, helium, etc., are chemically exceptionally INERT.

However, most gases—at least the atmospheric gases—are diatomic. To highlight this molecularity, chemists frequently refer to gases as dinitrogen and dioxygen. Halogens and chalcogens are both binuclear elements, though not all of them are gaseous under standard conditions.

No, inert gases do not form diatomic molecules; they exist as monatomic gases.

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.
