What characterizes ionic bonds?

• A. Sharing of electrons between atoms
• B. Transfer of electrons from one atom to another
• C. Equal sharing of electron pairs
• D. Spin coupling of unpaired electrons

Answer: (B)

Ionic bonds are characterized by the transfer of electrons from one atom to another. This occurs when one atom has a high electronegativity, strong enough to attract electrons from another atom with lower electronegativity. As a result, the atom that loses an electron becomes positively charged (a cation), while the atom that gains an electron becomes negatively charged (an anion). The electrostatic attraction between these oppositely charged ions forms the ionic bond. This process typically occurs between metals and nonmetals, where metals tend to lose electrons and form cations, and nonmetals tend to gain electrons and form anions. The transfer of electrons leads to the formation of a stable ionic compound, characterized by a lattice structure in solid form, which contributes to many of the properties observed in ionic substances, such as high melting and boiling points. The other options refer to different types of bonding. Sharing of electrons describes covalent bonds where two atoms share electrons. Equal sharing relates to nonpolar covalent bonds specifically, while spin coupling of unpaired electrons pertains to concepts in magnetism and does not define a type of chemical bond.
