I am comparing the ions BeS and BeO.
BeS...
d=229 pm
Force of attraction = -6.856x10^29 J/m
BeO...
d=199 pm
Force of attraction = -9.078x10^29 J/m
I used Coulumb's to find this. Can you explain this?... the reasoning why BeS has a greater attraction?

No, I can't. I would think the reverse. S is larger, the ions are farther apart, the attraction would be less for BeS than for BeO by my reasoning.
