The type of bond that does not involve the sharing of electron pairs is called an Ionic bond. In an ionic bond, one atom donates an electron to another atom, resulting in the formation of charged ions: cations (positively charged) and anions (negatively charged). This transfer of electrons leads to attractions between these oppositely charged ions, creating a stable compound. Ionic bonds typically form between metals and nonmetals, where the metal loses electrons while the nonmetal gains them. This type of bonding is essential in the formation of various compounds, including salts and minerals.
