Full Answer

Neon is considered the most noble of the gases, as it has the lowest reactivity in a group of elements with low reactivity. Elements react with each other to form groups of eight valence electrons. Neon has eight stable electrons in its natural state, so it has no reason to seek out electrons from other elements. Neon can be made to react artificially with fluorine under controlled laboratory settings.
