Generally, metals form cations. Generally, non - metals form anions. 5. Cations get attracted towards the negatively charged electrode in electrolysis. Anions get attracted towards the positively charged electrode in electrolysis. 6.Polyatomic ions. Polyatomic ions are molecular ions composed of two or more atoms bonded by covalent bonds and acting as a single unit, but unlike molecules, they have a net charge on them. The examples include cations like ammonium ion ( NH 4 + ), and hydronium ion ( H 3 O + ); and anions like hydroxide ion ( OH − ), and cyanide ion ( CN − ).The rules are simple, name the cation first and the anion second, giving the anion the -ide suffix. Cation (metal) first; Anion (nonmetal) second with -ide suffix; The problem is some metals have more than one stable charge state, and so for those metals (type 2 metals), we need to identify the charge in the name.
