First off, CHECK THE CHARGES!!!!!!! It makes a huge difference! Second, all you have to do is add the number of hydrogen atoms needed depending on the charge. For example, hydrochloric acid had one atom of chlorine and one atom of hydrogen because hydrogen has a charge of +1 and chlorine has a charge of -1 and their net charge needs to be 0.

Chemical Formulas
The way I remember most of my ions is by memorizing all of the chlorine ions then branching off from there. I also remember that ammonium and hydronium end in "ium" and they are the only two polyatomic ions with a +1 charge.
