Oh wow, just adding that extra proton to fluorine completely changes the chemistry of Neon. Neon, being one of the second Noble gases is very stable. So stable that it just doesn't like reacting with other elements. There are occasional rumours of a compound but it seems pretty unlikely. It is very well known for lighting that bears it name as neon lights.
