Here are the Polyatomic Ions that 2022-2023 students NEED TO MEMORIZE |
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 (S2- - sulfide ion) *Only Hydrogen has both, H1+ - Hydrogen ion and H1- - Hydride ion Part II : Here are the Polyatomic Ions that 2022-2023 students NEED TO MEMORIZE |
PLUS ONE CATION POLYATOMIC IONS: Ammonium NH41+ |
*Ammonium NH41+ (Only CATION POLYATOMIC IONS) Part III : Cations with More than One Charge and a Few Cations can figure out from Periodic Table (NEED TO MEMORIZE) *Copper (I) - Cu1+ *Copper (II) - Cu2+ *Iron (II) - Fe2+ *Iron (III) - Fe3+ *Silver - Ag1+ *Zinc - Zn2+ *Nickel - Ni2+ |
