D. Varlations of Polyatomic lons: 1. Polyatomic ions with oxygen included have multiple variations. The number of oxygen atoms included determines the naming scheme. 2. The charge of the lon is always the same as the main version no matter the number of oxygen atoms. 3. Main versions of ion always have: base root of ion and end with -ate examples: SO42 (sulfate); NO31 (nitrate) 4. One more oxygen than the main version always has: per-base root of ion-ate examples: SO52 (persulfate); NO41 (pernitrate) 5. One less oxygen than the main version always have: base root of ion and ond with -lte examples: SO32 (sulfite); NO21 (nitrite) 6. Two less oxygens than the main version always has: hypo-base root of ion -ite examples: SO22 (hyposulfite); NO1 (hyponitrite) How to determine what is a main version of a polyatomic ion: Outside of chart always has three (3) oxygen atoms for the main version.
