There are only two positive polyatomic ions: NH4+ is called the ammonium ion and Hg22+ is called the mercury(I) ion It is important to know that this is a list of polyatomic ions for your reference only. All of these ions may not be used during the semester in a direct fashion but can be used (for examples) to explain concepts....
