Neon is a noble gas and is unlikely to be found in ANY molecule, let alone a covalent one.
Ne is a gas - 1 molecule of Ne would be a particle
C, H, Se, Br, I, F, Cl, O, P, S, He, Ne, Ar, Kr, Rn
Neon (Ne) does not exist as a diatomic molecule. Fluorine (F), Chlorine (Cl), and Hydrogen (H) can form diatomic molecules (F2, Cl2, H2) due to their bonding characteristics, but Neon is a noble gas and exists as single atoms due to its stable electron configuration.
Neon (Ne) is a noblegas, as such it already has a filled electron shell (8 valence electrons) and don't form bonds to other atoms. So zero bonds, it is happy all by itself.
The noble gas that has the same electron configuration as the oxygen atom in a water molecule is neon (Ne). Both have a full valence shell with 8 electrons, making them stable and unreactive.
Cl2 is covalent. NaCl is ionic.
Neon is an inert (rarely reacting) non-metal. One of the reasons why is because it is located on the furthest family(column) to the right, all of which are Noble gases (A group of inert gases) and a gas cannot be a metal (though when a gas is condensed it can become a metal, but that doesn't happen in this particular case).
Is Ne a atom or molecule
Ne is definitely an atom.
The element you are referring to is neon (Ne). Neon is a nonmetal and a monatomic gas located in the third period of the periodic table.

Cl2 is a covalently bonded molecule because it is composed of two nonmetal atoms that share electrons. Air is a mixture of gases, with nitrogen and oxygen being the main components, and these are also covalently bonded molecules. Neon is a noble gas and exists as individual atoms, not molecules. Salt is an ionic compound composed of a metal and a nonmetal held together by ionic bonds.
Chlorine is a non-metal. It is found in group 7 of the periodic table of elements and has electronic configuration [Ne] 3s2 3p5.

Noble gasses, from group 18: He Ne Ar Kr Xe Rn
Helium (element 2 He) and Neon (element 10 Ne) are unlikely to form molecules because they are noble gasses and thus unreactive.
