Transition Metal Ion
Naming
IUPAC Nomenclature–
Roman numerals are used
to name those ions (and
only those) having more
than one possible charge.
Old Nomenclature –
-ous: ion that has the
lower charge
-ic: ion that has the higher
charge
Quiz 4: Polyatomic Ions – T41
Nitrite
NO2Nitrate
NO3Carbonate
CO3-2
Sulfite
SO3-2
Sulfate
SO4-2
Phosphite
PO3-3
Phosphate
PO4-3
Arsenate
AsO4-3
Chlorite
ClO2Chlorate
ClO3Bromite
BrO2Bromate
BrO3Iodate
IO3-
NOTE
-ite: lower number of
oxygen atoms
-ate: higher number of
oxygen atoms
Also – look at the charge
on each pair – it stays the
same!!
