This blog will cover and explain the specification for Edexcel triple science course 2013 Chemistry. Hope it helps :)
Do we need to know these off by heart? Will we not be given a sheet of ionic charges with the periodic table we're given at the beginning of the exams? Thanks.
Sadly Henry, we do need to know these off by heart.
Not entirely- you should be able to tell each element's charges by their placement on the periodic table.

how do you know charges by the periodic table m8
Didn't meant to comment
If the element is in group 1 it has a charge of + Group 2= 2+Group 3 = 3+Group 5 = 3-Group 6 = 2-Group 7 = -Group 8 = neutral
What's group 4?
There is no group 4
