Guida verificata passo dopo passo1
Identify the chemical formula of the molecule given, which is HF.
Understand that the subscript number after an element symbol indicates how many atoms of that element are present in one molecule.
In HF, there is no subscript after F, which means there is exactly one fluorine atom in one molecule of HF.
Therefore, the number of fluorine atoms in one molecule of HF is 1.
Confirm that the answer choices include 1, and select it as the correct number of fluorine atoms.
