Is there any techniques to naming cations and anions?

I find it hard to memorize common cations and anions so is naming them. Help!

Is there any techniques to naming cations and anions?
Cations are easy, except for "ammonium" (NH4+) most of the common ones are just the name of the metal, with a bracketed Roman number to indicate oxidation state if multiple ones are possible (eg iron (II) or iron (III)).





Anions with only one element (no additional oxygen) end in -ide, those with the most stable amount of oxygen end in -ate and those with somewhat less in -ite. Unstable anions with even more than the optimum oxygen start in per- while those with less than the -ite content use the hypo- prefix.





Examples:





NaCl = Sodium Chloride (salt)


NaClO = Sodium Hypochlorite (this is used in bleach)


NaClO2 = Sodium Chlorite


NaClO3 = Sodium Chlorate (formerly used as a weedkiller)


NaClO4 = Sodium Perchlorate
