Which statement best describes covalent bonding?

• A. A covalent bond is formed when electrons are shared between two atoms
• B. A covalent bond is formed by transferring electrons from one atom to another
• C. A covalent bond is the attraction between ions
• D. A covalent bond is a weak force that holds molecules together

Answer: (A)

Covalent bonding happens when atoms share electrons to fill their outer shells, creating a stable link that holds the atoms together in a molecule. By sharing electrons, each atom gains access to more electrons than it has by itself, which helps both achieve a fuller outer energy level. This type of bond is common between nonmetals and can be a single, double, or triple share, leading to different bond strengths. Covalent bonds are generally strong and form the structural backbone inside molecules; the presence of polar or nonpolar covalent bonds depends on how evenly the shared electrons are pulled by the atoms involved. Transferring electrons from one atom to another creates ions that attract each other, which describes ionic bonding, not covalent bonding. The idea of a simple attraction between ions reflects ionic bonds. Saying covalent bonds are a weak force would misrepresent them; the bond within a molecule is typically quite strong, while weaker forces like hydrogen bonds or van der Waals forces occur between separate molecules.
