For common monatomic ions see p 128 of the text.   See also Table 5.6 p 130.
You must know the names, formulas, spellings of all of these polyatomic anions.

The red ones are especially important and serve as a basis for other related ions.

"Hydrogen" anions (HPO4-2, HCO3-, etc.) follow a systematic pattern of naming
and charges derived by adding H+ to the base anion from the table below.
