Neon, with its configuration ending in s2p6, has eight valence electrons.

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. Neon exists as single atoms in its elemental form.

The neon atom, a noble gas, has a completely filled valence shell with an octet of electrons. It cannot become an anion by accepting another electron.

Neon Element Facts. The chemical element neon is classed as a noble gas and a nonmetal.

The Properties of Gases. Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.

Neon, Z=10 , has eight valence electrons. This closed shell configuration makes neon supremely difficult to oxidize, and difficult to reduce. The inertness, the lack of reactivity, of this Noble Gas, is a function of its electronic configuration.

Neon is a very pure atomic substance, identified as an atom - the smallest unit of measurement of a known material. But more importantly, it is a Noble Gas... meaning that as a NOBLE substance it will not combine with other types of atoms (to my knowledge) to form more complex molecules.

Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. Liquid neon is an important cryogenic refrigerant. It has over 40 times more refrigerating capacity per unit volume than liquid helium, and more than 3 times that of liquid hydrogen.
