Helium (He).

Reason: He has a full valence shell (1s^2), so it is a closed‑shell noble gas with no tendency to gain, lose, or share electrons. C, P and Na readily form covalent or ionic bonds under normal conditions. (Helium only shows extremely weak van der Waals interactions or exotic species under extreme conditions.)
