Can the ionic charge of any metal be determined from the position of the element on the Periodic Table?

Question

And also, what would a Lewis dot structure look like for Copper and Iodine?

Help with either question would be GREATLY appreciated.

Answer 1

I'm sorry, I can only answer one question bebcause I'm not sure how to do the Lewis Dot Structure on a computer.


yes, any element's charge can be figured out by the column its in.

column 1: +1
column 2: +2
column 3: +3
column 4: + or - 4
column 5: -3
column 6: -2
column 7: -1

The nobel gasses don't have a charge placed upon them
