The element that gains 3 electrons to fill its outermost energy level is **nitrogen**.
Nitrogen has 5 electrons in its outermost shell (2s² 2p³) and needs 3 more to reach a stable configuration of 8 electrons, which is the octet rule. The other elements listed either lose electrons (like calcium) or already have a full outer shell (like neon).
