Figuring out the Charge on Ions
To find the charge on ions we can either use the Periodic Table or, for polyatomic ions, a table of common ions.
For ions of individual elements, like Sodium, Nitrogen, or Oxygen, we can follow the trend on the Periodic Table. For example, ions in Group 1 have a 1+ charge. Sodium (Na) forms Na+ ions. Nitrogen (N) is N 3- and Oxygen (O) forms O 2- ions.
To figure out the charge on polyatomic ions we can either have them memorized or, if we are allowed by our instructor, look them up on a table of common polyatomic ions. For example, the sulfate ion is SO4 2-. The Nitrate ion is NO3 - .

Determining the charge on ions is a key skill in chemistry. It is used extensively in naming and writing formulas for chemical compounds, in net ionic equations, chemical bonding, etc. A good strategy is to memorize the pattern for ions in the Periodic Table first. Then memorize the most common polyatomic ions. Being able to quickly recall the charges ion ions will save time on exams, homework, and make life easier.

Pretty helpful, but still cannot figure out charges on polyatomic ions without a transition metal. Why do nitrate or sulfate have only a -1 or -2 charge when they are in higher negative charge groups? I would assume they would be 9- and 10-.
