**Polyatomic Ions

High priority ions duplicated for higher "flash frequency".

Polyatomic IonsPolyatomic Ions
formula for ammonium?*** NH4 (+1)
formula for sulfite?** SO3 (-2)
NO2 (-1) nitrite**
formula for chlorate?* ClO3 (-1)
formula for chlorite?* ClO2 (-1)
formula for perchlorate?* ClO4 (-1)
formula for hypochlorite?* ClO (-1)
formula for chromate?* CrO4 (-2)
formula for cyanide?* CN (-1)
formula for thiocyanate? SCN (-1)
formula for phosphite?** PO3 (-3)
formula for hydrogen phosphate?** HPO4 (-2)
formula for dihydrogen phosphate?** H2PO4 (-1)
formula for hydrogen sulfate?* HSO4 (-1)
formula for hydrogen sulfite? HSO3 (-1)
Aside from hydronium (H3O+), what's the only common polyatomic cation?*** Ammonium. Professors LOVE to test you on this one.
formula for acetate?** CH3COO (-1)
formula for bromite? BrO2 (-1)
formula for bromate? BrO3 (-1)
formula for chromite?* CrO2 (-1)
formula for hydronium?*** H3O (+1...water with an added H+)
formula for iodate? IO3 (-1)
formula for iodite? IO2 (-1)
formula for perbromate? BrO4 (-1)
peroxide** O2 (-2)
formula for sulfate?*** SO4 (-2)
formula for phosphate?*** PO4 (-3)
formula for carbonate?*** CO3 (-2)
formula for nitrite?*** NO2 (-1)
"Per___ate" has [one more, one fewer] O than "___ate"? one more
"___ate has [one more, one fewer] O than "___ite"? one more
"Hypo___ite" has [one more, one fewer] O than "___ite"? one fewer
How does charge differ between the ates, ites, per___ates and hypo___ites? The charge (almost always) stays the same, but the number of O changes.
formula for carbonate?*** CO3 (-2)
formula for hydroxide?*** OH (-1)
NH4 (+1) ammonium***
formula for chlorate?* ClO3 (-1)
Do any monoatomic ions end in "ite"? Nope, they are usually "ides" like chloride, fluoride, etc.
formula for nitrate? NO3 (-1)
formula for hydrogen carbonate?*** HCO3 (-1)
CO3 (-2) carbonate***
SO3 (-2) sulfite**
SO4 (-2) sulfate***
HCO3 (-1) hydrogen carbonate***
OH (-1) hydroxide***
ClO4 (-1) perchlorate**
ClO3 (-1) chlorate**
ClO2 (-1) chlorite**
ClO (-1) hypochlorite*
O2 (-2) peroxide*
CH3COO (-1) acetate**
CN (-1) cyanide**
NO3 (-1) nitrate***
BrO2 (-1) bromite
BrO3 (-1) bromate
H3O (+1) hydronium***
IO3 (-1) iodate
IO4 (-1) periodate
IO2 (-1) iodite
IO (-1) hypoiodite
PO3 (-3) phosphite**
Do any monoatomic ions end in "ate"? No. They are usually "ides" like chloride, iodide, etc.
formula for periodate? IO4 (-1)
