A chemical bond that involves sharing electrons between two nonmetal atoms is called a covalent bond.

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

Answer: (B)

The main idea here is that bonds formed by sharing electrons occur between nonmetal atoms, which is exactly what a covalent bond is. When two nonmetals come together, their electrons are shared so both atoms can reach a more stable, filled outer shell. That sharing creates a discrete molecule, and the description in the statement fits covalent bonding well. In contrast, ionic bonds come from transferring electrons, typically between a metal and a nonmetal, producing ions held together by electrostatic attraction. Metallic bonds involve a lattice of metal cations with a sea of delocalized electrons. Hydrogen bonds aren’t true bonds formed by electron sharing; they’re strong attractions between a hydrogen atom bonded to a highly electronegative atom and another electronegative atom in a nearby molecule, an intermolecular force. Examples of covalent bonds include H2, O2, and the covalent bonds within H2O molecules.
