Question

please tell me the trick of revising its ions and charges​

Answer 1

I have a chemistry test coming up and I might need to know the charge that goes with the different ions like SO4SOX4 has −2−2, NO2NOX2 is −1−1 and PO4POX4 is −3−3. Is there an easy way to remember this by looking at the periodic table or something like remembering that the second row elements are all going to be something−O3something−OX3 and the next row is all something−O4something−OX4 for the -ate endings (except ClCl which is the odd man out). It will make writing out the different acid combos easier, if I can remember the charge difference that needs offsetting by the hydrogen.

I'm just trying to lay down some associative triggers for myself.

Follow me if u have any douts so i can help you ..

Thankyou and have a nice day
