Part I : Ions Directly from Periodic Table

All metals, charges are positive and is the number of column from Left to right of Periodic Table (Na¹⁺ - sodium ion)
All non-metals, charge is negative and is the number of column from Right to Left from Noble Gases (S^2- - sulfide ion)
Only Hydrogen has both, H¹⁺ - Hydrogen ion and H^1- - Hydride ion

Part II : Here are the Polyatomic Ions that 2022-2023 students NEED TO MEMORIZE

Part III : Cations with More than One Charge and a Few Cations can figure out from Periodic Table (NEED TO MEMORIZE)
