Which type of bond involves the sharing of electron pairs between atoms?

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

Answer: (B)

A covalent bond is characterized by the sharing of electron pairs between atoms. This type of bonding typically occurs between nonmetal atoms, which have similar electronegativities. When these atoms share electrons, they can achieve a full outer shell of electrons, leading to greater stability in the resulting molecule. In the context of atomic interactions, covalent bonds allow atoms to form molecules with distinct physical and chemical properties. For instance, in a water molecule (H₂O), the oxygen atom shares electrons with two hydrogen atoms, resulting in a stable molecular structure. Understanding this sharing mechanism explains the formation of various substances and their behaviors in different environments. The other types of bonds listed involve different interactions, such as ionic bonds, where electrons are transferred from one atom to another, and metallic bonds, which involve a sea of shared electrons among a lattice of metal atoms, but do not specifically involve the localized sharing of electron pairs as seen in covalent bonds. Hydrogen bonds are weak attractions that occur between polar molecules and are not bonds in the conventional sense since they do not involve direct sharing or transferring of electrons.
