Which statement best describes covalent bonds?

• A. Transfer of electrons between two nonmetals
• B. Sharing of electron pairs between atoms
• C. Formation of metal alloys
• D. Bonding due to electron repulsion

Answer: (B)

Covalent bonds are formed when two or more atoms share pairs of electrons. This sharing occurs most commonly between nonmetals, allowing each atom to achieve a full outer electron shell, which enhances stability. In a covalent bond, the shared electrons are attracted to the nuclei of both atoms, which helps hold the atoms together. This process differs from other bonding methods, such as ionic bonding, where there is a complete transfer of electrons from one atom to another. Covalent bonds also contrast with metallic bonds and the concept of alloys, which involve different interactions and structures entirely. Additionally, bonding due to electron repulsion refers to different phenomena, as repulsion primarily influences how atoms and molecules approach one another rather than the formation of bonds.
