WebHow many electrons do elements in groups 14 and 17 need to gain to achieve a stable configuration? Show Answer ... These elements, including hydrogen (H), lithium (Li), and sodium (Na), all have one electron in their outermost shells. That means that they can achieve a stable configuration and a filled outer shell by donating or sharing one ...
