Question

what kind of bond will have a prefix? (eg. mono, di, tri...) *
ionic
covalent
which kind of bond happens between two nonmetals? *
ionic
covalent
metal

Explanation:

First Question:

In chemical nomenclature, covalent bonds (formed between nonmetals or nonmetal and metalloid) use prefixes like mono, di, tri to indicate the number of atoms of each element in the molecule. Ionic bonds (between metal and nonmetal) use the name of the cation and anion without such prefixes. So covalent bonds have prefixes.

Ionic bonds form between a metal and a nonmetal (due to transfer of electrons). Covalent bonds form when two nonmetals (or a nonmetal and metalloid) share electrons. "Metal" is not a bond type. So the bond between two nonmetals is covalent.

Answer:

B. Covalent
