Why conductors conduct heat and electricity while insulators are known as poor conductors?

Conductors conduct heat and electricity well because they have delocalised electrons in their structure. Insulators, on the other hand, do not have delocalised electrons and therefore do not conduct heat and electricity as a conductor, although they do conduct to some extent.

What are the best mediums to conduct electricity?
Most metals are well known to be good conductors of heat. Examples of such metals are aluminum and copper. Objects that do not conduct electricity are known as insulators.
What does it mean if something is a good conductor?
A good conductor is a substance that will easily carry loose ions, also known as electricity. Many metals are good conductors. Conductors have many modern applications. Any wire that carries an electrical current has to be a conductor of some sort. On the contrary, substances that do not conduct electricity are known as insulators. Rubber is a very common insulator.
Is oxygen a poor conductor of electricity?
Oxygen is a poor conductor of electricity and also heat. It is known to support combustion but its state does not allow it to conduct electricity.
Is the tungesten filament a good conductor?
Tungsten is a good conductor of electricity. If it was a poor conductor and highly resistive then electricity would never pass through it as a filament inside a light bulb, therefore, it would never glow.
What are 3 examples of an insulator?
Insulators of electricity: A person wearing rubber boots stepping on an exposed wire without getting electrocuted. Insulators of heat: A styrofoam cup containing hot water. It does not heat up or burn your hand a lot. In fact, it is so minimal that you hardly notice it.

What are non conductors of electricity known as?
could it be insulators?

What are semi-conductive metalloids?
Metalloids are known as semi-conductors meaning they can conduct electricity, but they are not good conductors. Metals are good conductors. Non-metals are bad conductors.
What materials would be poor conductors of electricity?
Materials known as 'insulators' would be the worst. They include such substances as glass, ceramic, rubber, plastic, wood, and pure water.
What is the difference between conductors and ilsulators?
CONDUCTOR: those objects which can pass electricity through them is known as conductors. the conductors can pass electricity through them due to free electrons present in them. for example: iron, copper, aluminium etc.INSULATOR: those objects which can not pass electricity through them is called insulator. the insulators can't pass electricity due to less or absence of free electrons. for example paper, wood, rubber etc
What are conductors and insulators of electricity?
Conductors are materials that pass electrical current easily, that is, with low resistance. Insulators are materials that do not pass electrical current easily, that is, they have high resistance. Conductors are ordinarily metals, and insulators are ordinarily nonmetals. Some examples of conductors are: Silver, Copper, Carbon, and Aluminum. Some examples of insulators are Glass, Nylon, and Wood (as well as Air and Vacuum). Conductivity is a function of the mobility of Electrons in the materials in question. Conductors have high mobility and conductors have low mobility. Semiconductors are materials that have some properties of both conductors and insulators. Germanium and Silicon are well known semiconductors. Superconductors are materials that pass electrical current with zero resistance. All known superconductors perform this function only at very low temperatures, far below those encountered in Earth environments (i.e. from around 77 degrees above absolute zero down, or, in other words, below about -320 degrees F).
Are nonmetals semiconductors?
Some are, such as silicon and germanium. Others are non-conductors known as insulators, such as glass.
What are the substances that conduct heat are known as what?
They are called good thermal conductors.
Compare conductor and insulator?
Conductors and insulators are different and simalar in many ways.Two ways they are simallar are they both have electrons and have something to do with electricity.Three ways they are different that conductors let heat and electricity go through it .On the other hand insulators do not let heat or electreicity go through it easily.Another way is conductors transfer eelectrons easily but meanwhile the insulator psses on electrons with difficulty.One last thing is that conductors are not current but insulators are current.

What solution conducts to electricity is called what?
A solution which can conduct electricity is known as an electrolyte.
What is heat directly transferred through?
Heat is directly transferred through metals, also known as conductors. They conduct heat energy and electricity. This is why wires are made out of the metal copper, because it is an efficient conductor.
