Which type of bond involves the attraction between oppositely charged ions?

The attraction between oppositely charged ions defines an ionic bond. This type of bond forms when an electron is transferred from one atom to another, resulting in the formation of ions. One atom becomes positively charged (a cation) while the other becomes negatively charged (an anion). The electrostatic force between these oppositely charged ions creates a strong bond, which is characteristic of ionic compounds.

In contrast, a covalent bond involves the sharing of electrons between atoms rather than the transfer of electrons, leading to neutral atoms rather than charged ions. Metallic bonds, on the other hand, occur between metal atoms, where electrons are shared in a "sea of electrons," allowing for properties like conductivity and malleability but not involving ionic attraction.

Therefore, the definition and formation process of an ionic bond clearly align with the description of attraction between oppositely charged ions, making that the correct choice.
