The that end in -ide include, ##OH^-## hydroxide, ##O_2^-## peroxide, ##CN^-## cyanide, ##NH_2^-## amide and ##HS^-## hydrogen sulfide.
The -ide suffix, is usually reserved for monatomic anions.
Non-metal ions like oxygen, fluorine and chlorine take on the -ide and become oxide, fluoride and chloride.
Most of the polyatomic ions end in -ite and -ate. ##NO_3^-## nitrate, ##ClO_2^-## chlorite, etc…
The positive monatomic ions keep their common name, however metals can use the -ic and -ous suffixes in ##Fe^(+2)## ferrous and ##Fe^(+3)## ferric, etc...
There is one positive polyatomic ##NH_4^-## ammonium which uses the -ium suffix.
I hope this was helpful. SMARTERTEACHER
