Inert Gases - Diatomic?

Question

I was wondering do inert gases exist as diatomic gases, i.e Ne2 instead of just Ne?

Answer 1

Nope

Answer 2

nope the only diatomics are N, O, F, Cl, Br, I, and H

Answer 3

No, the inert gases are not diatomic.  The diatomic gases are the "HAIROGENS"

H-AIR-OGENS = hydrogen, air (O2 and N2), and the halogens

Lets think about why the halogens are diatomic and the inert gases aren't.  Why would one chlorine atom want to bond to another chlorine atom?

Chlorine (like all the halogens) has seven valence electrons, one of which is unpaired.  By bonding with another chlorine atom and sharing a pair of electrons (covalent bond) between them, each chlorine "thinks" it has an octet of electrons and is therefore more stable.

Now, the inert gases ALREADY have an octet of electrons and they have no need to bond to another element in order to get an octet of electrons.  Therefore the inert gases are not diatomic.
