1. Start with the prefix "hydro-".

2. Use the root name of the nonmetal element.

3. End with the suffix "-ic acid".

Here are some examples:

* HCl: hydro + chlor + ic acid = hydrochloric acid

* HBr: hydro + brom + ic acid = hydrobromic acid

* HI: hydro + iod + ic acid = hydroiodic acid

* HF: hydro + fluor + ic acid = hydrofluoric acid

Important Note: This naming convention only applies to binary acids, which are acids composed of hydrogen and a nonmetal.
