WebThe metallic bond can be described as the attractive force present between negatively charged mobile electrons and positively charged metallic ions. This force of attraction is used to hold the metal atoms together in the metallic crystal. Metallic bond examples are: Sodium Aluminium Magnesium Copper Iron Web14 de ago. de 2024 · Ionic bonds form when metals and non-metals chemically react. By definition, a metal is relatively stable if it loses electrons to form a complete valence shell and becomes positively charged. Likewise, a non-metal becomes stable by gaining electrons to complete its valence shell and become negatively charged.
