Detailed explanation-1: -Once dissolved or melted, ionic compounds are excellent conductors of electricity and heat because the ions can move about freely.

Detailed explanation-2: -Ionic materials are good conductors of electricity if they are in their liquid state or are dissolved in a polar solvent (like water).

Detailed explanation-3: -Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

Detailed explanation-4: -In good conductors of electricity, the type of bonding that exists is metallic bonding.

Detailed explanation-5: -Metallic bonds are the force of attraction between positive metal ions and the valence electrons that are constantly moving around them. Metals have relatively low electronegativity, or attraction to electrons. This makes metals good conductors of electricity.
