Which of the following is TRUE about ionic solids?
Ionic solids have high vapor pressures because they have very strong intermolecular forces holding the molecules together in a crystalline structure.
Ionic compounds are excellent conductors of electricity because they are composed of electrically charged ions, and conductivity involves charged particles.
Polar solvents are the best choices to dissolve ionic compounds because those solvents have permanent charge separations like the ions in the ionic crystal structure.
Ions with a bigger atomic radius tend to be more strongly attracted to each other because there are more electrons to be attracted to the nucleus of other atoms.
