The Truth About Ionic Solids

APCHEM-G54NLE

Which of the following is TRUE about ionic solids?

A

Ionic solids have high vapor pressures because they have very strong intermolecular forces holding the molecules together in a crystalline​ structure.

B

Ionic compounds are excellent conductors of electricity because they are composed of electrically charged ions, and conductivity involves charged particles.

C

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.

D

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.
