Good day everyone,
In my science textbook, there is a list of Polyatomic Compounds with their respective Ionic Charges. I was wondering if you could tell me how I can derive the ionic charge from scratch.
For example, NH4 has a charge of +1. Could you please tell me how I find out without knowing beforehand that it is +1? My mistake, I meant to type +1. Thanks for correcting it!
Thanks a lot in advance.
James
