Verified step by step guidance1
Understand that hydrofluoric acid is an acid formed by hydrogen and fluorine atoms.
Recall that acids typically have the general formula HX, where H is hydrogen and X is a nonmetal or polyatomic ion.
Identify the symbol for fluorine, which is 'F', and combine it with hydrogen 'H' to form the acid.
Check the options to see which formula correctly represents one hydrogen atom bonded to one fluorine atom.
Recognize that the correct chemical formula for hydrofluoric acid is \(HF\), indicating one hydrogen atom and one fluorine atom.
