Polyatomic Ions

Postby Louis Zhao 4C » Sun Oct 28, 2018 6:34 pm

Do we need to memorize the chemical formulas for common polyatomic ions such as Ammonium, Carbonate, Nitrate etc. or will their chemical formulas be given to us whenever they come up on a quiz or test.

You will most likely be better off knowing the common ones. If they aren't provided it will hugely benefit you and if they are it will save a lot of time just knowing them.

Even if we aren't supposed to specifically memorize a list, I do think it is always good to memorize the big name ones (such as Nitrate, Carbonate, etc) since you might need them in the future for other chemistry related classes.

At the beginning of the quarter Dr. Lavelle said we didn't have to know them now, but that later we would. My PLF also said that with time, after doing many problems, you would probably end up memorizing them anyways. Don't worry about it too much , but do try to memorize them.

Is there a list of common polyatomic ions we should memorize?
