Chemistry
Ions and Polyatomic ions students are responsible to know by memory:
There will be a quiz on naming and writing formulas of ionic compounds that will include these ions. You will
only be able to look at a generic periodic table for this quiz.
 All representative elements (by location on periodic table)
 Transition metals:
Silver
Ag+
Cadmium
Cd2+
Zinc
Zn2+
Other transition metals (by “roman numeral” i.e. Copper (II) = Cu2+)


Polyatomic Cations
ammonium
NH4+
hydronium
Polyatomic Anions
acetate
C2H3O2carbonate
CO32hydroxide OHsulfate
SO42nitrate
NO3
sulfite
SO32nitrite
NO2
cyanide
CNbicarbonate HCO3- (or hydrogen carbonate)
H3O+
phosphate
phosphite
PO43PO33-
Strategies:
Create flashcards of each ion (name on one side, symbol and charge on the other).
Use “Quizlet” to either create your own flashcards and quiz or search for one that already exists.
