What is the difference between electrical conductors and insulators?

What makes certain materials better conductors than others?
Metals have free electrons that are not bounded to the atoms. These electrons are free to move around within the metal, colliding with the metal atoms and transferring heat to them efficiently. This makes metals better conductors of heat than most other materials.
Why graphite is good conductor of electricity?
Each carbon atom is bonded into its layer with three strong covalent bonds. This leaves each atom with a spare electron, which together form a delocalised ‘sea’ of electrons loosely bonding the layers together. These delocalised electrons can all move along together – making graphite a good electrical conductor.
Why is air not a good conductor?
Air may be a bad conductor of heat because its molecules aren’t in continuous contact with one another. Air molecules are too far to disperse heat to at least one another efficiently.

What does a poor conductor of heat mean?
Basically, when it comes to conducting heat, not all substances are created equal.
