insulator
Anything that is classified as a conductor will allow the flow of electrons.
Heat moves easily through materials with delocalised electrons, that is electrons which are free to move through the substance. This happens in metals and graphite.
Materials that allow energy to flow easily through it are called conductors.
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. A conductor. It lets heat and electrical current easily.

A material through which negatively charged particles flow easily is called a conductor. Conductor materials have a large number of free electrons that are able to move within the material, allowing the easy flow of electric current. Examples of good conductors include metals like copper, aluminum, and silver.

An insulator is a material through which electrons do not easily flow. Insulators have a very high resistance.AnswerInsulators behave in the way they do because they contain insufficient numbers of charge curriers to support conduction. It has nothing to do with electrons being 'unable to flow easily'!
A conductor
insulator...as opposed to a conductor which does allow electrons to travel freely within it.

Electrons cannot easily move through a type of material called electrical insulators. These materials tend to be plastics or rubber. Just think of the coating on wires in your home for example

Gold, silver, copper, aluminium, iron, and lead are all quite good. Most metals carry electrons easily. A material that does that is called a good "conductor".
