Verified step by step guidance1
Identify the chemical formula of carbon tetrafluoride, which is \(\mathrm{CF_4}\).
Understand that the subscript number in a chemical formula indicates the number of atoms of that element in one molecule.
Look at the subscript next to fluorine (F) in \(\mathrm{CF_4}\), which is 4.
Recognize that this means there are 4 fluorine atoms bonded to one carbon atom in the molecule.
Conclude that the number of fluorine atoms in one molecule of carbon tetrafluoride is 4.
