Molecular Compounds: non-metal + non-metal -> through covalent bonding

• A. Non-metal + non-metal -> covalent bonds
• B. Metal + non-metal -> covalent bonds
• C. Non-metal + metal -> hydrogen bonds
• D. Metal + metal -> metallic bonds

Answer: (A)

When nonmetals bond, they tend to share electrons because their electronegativities are similar enough that neither atom gives up electrons completely. That sharing creates covalent bonds, which hold together discrete molecular units and give molecular compounds like water, methane, or carbon dioxide their characteristic structures. Ionic bonds arise from electron transfer between a metal and a nonmetal, forming ions that attract each other. Metallic bonds come from a delocalized pool of electrons around metal atoms. Hydrogen bonds are a type of intermolecular interaction, not the primary bonding that forms a molecule between nonmetals. So the description non-metal + non-metal -> covalent bonds best captures how these compounds are formed.
