Verified step by step guidance1
Identify the central atom in the polyatomic ion. In this case, it is fluorine (F).
Determine the number of oxygen atoms bonded to the central atom. Here, there is one oxygen atom (O).
Recall the naming convention for oxyanions: the prefix 'hypo-' and the suffix '-ite' are used for the oxyanion with the least number of oxygen atoms.
Combine the prefix 'hypo-', the root of the central atom 'fluor', and the suffix '-ite' to form the name 'hypofluorite'.
Verify that the name 'hypofluorite' corresponds to the given ion FO–, as it follows the naming rules for oxyanions with one oxygen atom.
