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