Which of the following statements about chemical bonds is true?

• A. Hydrogen bonds are stronger than covalent bonds.
• B. Metallic bonds occur only between nonmetal atoms.
• C. Ionic bonds involve the transfer of electrons from one atom to another.
• D. Covalent bonds are formed by the complete loss of electrons.

Answer: (C)

Verified step by step guidance

1. Review the nature of each type of bond mentioned: hydrogen bonds, covalent bonds, metallic bonds, and ionic bonds.
2. Understand that hydrogen bonds are a type of intermolecular force and are generally weaker than covalent bonds, which involve sharing electrons between atoms.
3. Recall that metallic bonds occur between metal atoms, not nonmetals, where electrons are delocalized over a lattice of metal cations.
4. Recognize that ionic bonds form when electrons are transferred from one atom (usually a metal) to another (usually a nonmetal), resulting in oppositely charged ions that attract each other.
5. Note that covalent bonds involve the sharing of electrons between atoms, not the complete loss of electrons, which distinguishes them from ionic bonds.
