Does the chemical element neon consist of a molecule? For example, oxygen consist of two atoms together. But is that the same with neon?

    $\begingroup$ Are you asking if an atom of Neon is classified as a "molecule"? Or are you asking if there are molecules which contain Ne atoms? $\endgroup$ – ManishEarth Sep 8 '13 at 10:58

Since neon is a noble gas, it has its full share of valence electrons, which makes it unlikely to bond with other atoms. Under certain conditions other noble gases, specifically xenon and krypton, can form compounds in extreme temperatures and pressures.

See the Wikipedia article on noble gases,

[the noble gases] are all monatomic gases under standard conditions

and, according to the article

Neutral compounds in which helium and neon are involved in chemical bonds have not been formed

  • $\begingroup$ I think the question is asking if a monoatomic molecule is ... well ... a molecule. $\endgroup$ – ManishEarth Sep 8 '13 at 10:49
  • $\begingroup$ @ManishEarth Hmm, well, true, that's how it reads, but I think this is what the OP is actually asking about. Thanks, I have an "it's" problem, doctors are checking into it :P $\endgroup$ – jonsca Sep 8 '13 at 10:51
  • $\begingroup$ Then what keeps solid, frozen neon together? $\endgroup$ – Eric Brown Sep 10 '13 at 4:36
  • $\begingroup$ @EricBrown that's a different (and interesting) question :) $\endgroup$ – F'x Sep 10 '13 at 7:47
  • $\begingroup$ @EricBrown So known van der Waals forces. They have different nature than covalent bonding, and are much, much weaker. $\endgroup$ – permeakra May 28 '14 at 6:42

Neon exists as single atoms in its elemental form. It is a noble gas, and as @jonsca said, that means (for various reasons) that it is extremely difficult for it to form bonds (I don't know of any neon compounds).

I think the confusion may be coming from a missing definition: what is a molecule?

A molecule is two or more atoms joined by covalent bonds.

Since neon exists as solitary atoms, it is not a molecular element.
