Between nonmetals, which type of bond is formed by sharing electrons?

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

Answer: (B)

When nonmetals bond, they typically share electrons to fill their outer electron shells, forming covalent bonds. This sharing happens because nonmetals have high electronegativity and similar tendencies, so neither atom completely donates or accepts an electron from the other. Instead, the bonded atoms share one or more pairs of electrons, creating a molecule such as H2, O2, or CH4. Ionic bonds involve transferring electrons from a metal to a nonmetal, producing ions that attract; metallic bonds occur in metals with a lattice of positive ions in a sea of delocalized electrons; hydrogen bonds are strong attractions between a hydrogen attached to a highly electronegative atom and another electronegative atom nearby, not a true bond between atoms themselves.
