The response "They have a full valence electron shell" is correct. Noble gases have a full valence electron shell, meaning that their outermost energy level is completely filled with electrons. This configuration makes them very stable and unlikely to gain or lose electrons. As a result, noble gases have little to no tendency to react or form compounds with other elements.
