Quiz will be on _______________________

NOTE: Spelling counts! Capitalization counts on symbols!!!! In a symbol, the first letter is ALWAYS a capital letter. If the symbol has two letters, the second is ALWAYS a lower case letter.

Polyatomic Ion List – Chemistry I Honors

+1

ammonium, NH4+

-1

acetate, C2H3O2-, or CH3COO -

bromate, BrO3-

chlorate, ClO3-

chlorite, ClO2-

cyanide, CN-

hydrogen carbonate, HCO3- (also called bicarbonate)

hydroxide, OH-

hypochlorite, ClO-

iodate, IO3-

nitrate, NO3-

nitrite, NO2-

permanganate, MnO4-

perchlorate, ClO4-

thiocyanate, SCN -

-2

carbonate, CO3 -2

chromate, CrO4 -2

dichromate, Cr2O7 -2

oxalate, C2O4 -2

peroxide, O2 -2

sulfate, SO4 -2

sulfite, SO3 -2

-3

phosphate, PO4 -3

phosphite, PO3 -3

arsenate, AsO4 -3

-ite is one less oxygen than the –ate

Hypo- is one less oxygen than the –ite

Per- is one more oxygen than the –ate

Hydrogen can be added to -2 or -3 ions to make a “new ion” i.e. H2PO4 –1 is dihydrogen phosphate (note the – charge went up 1 for each H+ added)
