Best Answer

HCO3 - CO3 2-

CLO -

FLO -

BrO3 -

IO3 -

NO3 -

PO4 3-

SO4 2-

These are "ate" ions

if you subtract one oxygen by adding one more hydrogen, this would make it "ite' ion. There is -1 charge; subtract one from the charge.

ex. CO 3 2- turns into HCO3 -

An example of a polyatomic ion is the sulfate ion (SO4^2-), which consists of one sulfur atom bonded to four oxygen atoms. It carries a net charge of 2- due to the presence of two additional electrons compared to the number of protons.
