Which type of bond usually occurs between two nonmetal atoms?

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

Answer: (B)

Covalent bonds typically occur between two nonmetal atoms because they involve the sharing of electron pairs between these atoms. Nonmetals, which are found on the right side of the periodic table, have high electronegativities and a strong tendency to attract electrons. When two nonmetals bond, instead of transferring electrons as in ionic bonding, they prefer to share electrons to achieve a full outer shell, following the octet rule. This sharing allows both atoms to gain stability. In contrast, ionic bonds occur primarily between metals and nonmetals, where there is a complete transfer of electrons, resulting in positively and negatively charged ions. Metallic bonds involve the sharing of electrons in a 'sea of electrons' among metal atoms, which is quite different from the behavior of nonmetals. Hydrogen bonds are a type of weak intermolecular force that can occur between molecules, but they are not considered a primary bonding type between atoms; instead, they usually occur when a hydrogen atom covalently bonded to a highly electronegative atom interacts with another electronegative atom. Thus, covalent bonds are the characteristic bonds formed between nonmetal atoms.
