There are many, but the two you're likely being asked for are:
- Hydroxide (
#OH^-# ) - Ammonium (
#NH_4^+# )
Explanation:
There are many polyatomic ions that don't end in "-ite" or "-ate". For example:
- Hydroxide (
#OH^-# ) - Ammonium (
#NH_4^+# ) - Cyanide
#(CN^-)# - Peroxide (
#O_2^(2-)# )
The first 2 are likely the ones that you're being asked for -- they're extremely common across general chemistry, and it will do you credit to have them memorized.
Hope that helped :)
