Ionic bonds are typically formed by which pairing of elements?

• A. Ionic bonds typically occur between metals and nonmetals.
• B. Ionic bonds typically occur between nonmetals only.
• C. Ionic bonds occur only in noble gas compounds.
• D. Ionic bonds are the same as covalent bonds.

Answer: (A)

Ionic bonds form because of electron transfer between atoms with very different tendencies to gain or lose electrons. Metals tend to lose electrons easily, becoming positively charged ions, while nonmetals readily gain electrons, becoming negatively charged ions. When the metal donates electrons to the nonmetal, those oppositely charged ions are held together by strong electrostatic attraction, creating an ionic bond. This metal–nonmetal pairing explains why ionic bonding is typical, as seen in compounds like table salt. In contrast, bonding between nonmetals usually involves sharing electrons (covalent bonds), noble gases don’t commonly form bonds, and ionic bonds are not the same as covalent bonds.
