Why are ionic solids poor conductors of electricity?

Non metallic elements show properties of non-malleability,non-lustrous and poor conduction of heat and electricity (Except Graphite).

Ionic solids are non-molecular. Each cationic particle is electrostatically bound to every anion in the solid. Of course there is electrostatic repulsion between like charges, but if you sum up...

Metals are good conductors of electricity and heat. the text doesen't tell anymore and Z may be one of abaut 90 known metals, in the left area of . X,...

Metals are excellent conductors because the atoms in a metal form a matrix through which their outer electrons can move freely. Instead of orbiting their respective metal atoms, they form...

Ionic substances are made up of positively charged cations and negatively charged anions, held in a 3D lattice by strong electrostatic forces of attraction between the ions. For example, let's...

Metals are $"malleable"$, capable of being hammered into a sheet, and $"ductile"$, capable of being drawn out into a wire. This workability makes metals the premier materials for making tools....

because covalent bonds are formed by sharing of electrons..they don't have a free electron that is required for electricity transfer(electricity is the flow of free electrons!) thus they re bad...

A solid ionic substance is composed of an infinite array of positive and negative ions held together by strong electrostatic forces. The ions are NOT free to move. Once these...

have low forces of attraction between their molecules (i.e. one H2O molecule isn't as attracted to another H2O molecule than the oppositely charges ions are in an ionic compound)....

Given: What solids are the best heat conductors? If you look at a thermal conductivity (units: $[W/(mK)]$)table you will see the following data at $ 25^@ C$ diamond = 1000...
