Noble gases have a completely filled outermost shell, making them highly stable and not likely to react with other elements. However, if they were to react, they would require a great deal of energy input to do so. Fluorine is an extremely reactive element with a high electronegativity value. Neon, being the smallest noble gas, has a full outermost shell and thus, it is least likely to react with fluorine.
