Bond between oppositely charged ions.

• A. Covalent Bond
• B. Hydrogen Bond
• C. Ionic Bond
• D. Metallic Bond

Answer: (C)

Oppositely charged ions attract through electrostatic forces, which creates an ionic bond. This happens when electrons are transferred from one atom to another, producing a positively charged cation and a negatively charged anion that stay bound together. Ionic bonds are typical between metals and nonmetals and give compounds high melting points and the ability to conduct electricity when melted or dissolved, since the ions can move. Covalent bonds rely on sharing electrons rather than full charge separation. Hydrogen bonds are weaker attractions between a hydrogen atom and another electronegative atom within a molecule. Metallic bonds involve a lattice of metal ions in a sea of delocalized electrons, not discrete ions held together by electrostatic attraction.
