Can someone explain how to do a problem like this?
Which of the following pairs would have the greatest coulombic attraction in a solid compound?
1. mg2+, S2-
2. mg2+, se2-
3.mg2+, O2-

Please first analyze the problem before getting panic.
Observation: the positive ion is the same, and the negative ions in the same group. Obviously, Se2- ion is bigger than S2- ion which is big than O2- ion.
Do you know that coulombic attraction
is reversely proportional to the square of the distance which is directly related to the ion radius?
Hence the answer: (3).
