Question

how do ionic bonds affect the properties of ionic compounds?

○ the bonds weakly hold ions together, increasing the melting point.
○ the bonds strongly hold ions together, reducing the boiling point.
○ the bonds prevent ions from moving throughout the crystal, so a solid ionic compound is a poor conductor.
○ the bonds prevent electrons from moving throughout the crystal, so a solid ionic compound is a good conductor.

Explanation:

compounds poor electrical conductors. The other options are incorrect: ionic bonds are strong (so they increase melting/boiling points, not decrease), and they restrict ion (not just electron) movement, which does not create good conductivity in solids.
