Explanation:

In chemical nomenclature, when naming binary molecular compounds (like those with fluoride as the anion in some cases, or for molecular fluorine compounds), the prefix "mono - " is used for one atom of the first element (or when there's one fluoride in a context where prefixes apply, though fluoride as an anion in ionic compounds doesn't use prefixes, but in molecular compounds like \( \text{OF}_2 \) is oxygen difluoride, but for \( \text{F}_2 \) it would be diatomic, but if we consider a compound like \( \text{NF}_3 \) is nitrogen trifluoride, but for a single fluoride in a molecular context where the first element has one atom, "mono - " is the prefix for one. Among the options, "mono - " is the correct prefix for one atom (e.g., in \( \text{HF} \) if we were using molecular prefixes, but actually \( \text{HF} \) is ionic, but in molecular compounds like \( \text{OF}_2 \) is oxygen difluoride, \( \text{NF}_3 \) nitrogen trifluoride, \( \text{CF}_4 \) carbon tetrafluoride, \( \text{PF}_5 \) phosphorus pentafluoride. But if we have a compound with one fluoride and one of another element (molecular), like \( \text{XF} \) (where X is a non - metal), it would be X mono - fluoride. The other prefixes: tri - is for three, tetra - for four, penta - for five. So "mono - " is the correct prefix here.

Answer:

mono-
