Science Half Yearly Flashcards | Quizlet

A metal and a non-metal exchange electrons in order to have a complete valence shell, and become stable. The metal becomes a positively charged ion (loses electron/s), while the non-metal becomes a negatively charged ion (gains electron/s). Ionic compounds are formed by the attractive force between the opposite charges of these ions.
