In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators. In copper, the valence electrons are essentially free and strongly repel each other. Any external influence which moves one of them will cause a repulsion of other electrons which propagates, "domino fashion" through the conductor.
Simply stated, most metals are good electrical conductors, most nonmetals are not. Metals are also generally good heat conductors while nonmetals are not.

∙ 15y agono it is a good conductor , non-metals are good insulators.
Wiki User
∙ 13y agoNo, metals are conductor and a conductor is a poor insulator because it has a low resistance to the flow of electric current or thermal energy.
Wiki User
∙ 9y agoMetals are not insulators, they are conductors. This is true because metals permit the flow of electrical current and heat.

∙ 15y agoAll metals are bad insulators since they conduct heat well.

Is magnesium a insulator?
yes
What does Good electrical insulator mean?
An insulator is a material that does not conduct well, so an electrical insulator is a material that does not conduct electricity well. A metal is a bad electrical insulator as it has delocalised electrons, therefore conducts electricity, but most plastics and materials like rubber do not conduct electricity, so they are good electrical insulators. Hope that makes sense and helps? :3AnswerAn insulator is a material with insufficient free charge carriers to support conduction.
Is sliver a conductor or insulator?
Like any metal, silver is a good conductor - both of heat, and of electricity.
Is a metal spring a conductor or insulator?
Most metal springs (steel, aluminum, etc) are conductors.
Is a silver spoon better conductor than a balloon filled with helium?
A very good conductor.
Is dirt a good insulator?
is foam dirt an metal a good insulator
What is a good insulator for a metal wire?
A good insulator would be rubber or plastic.
Is a metal saucepan a good insulator?
Yes. Metal is a good conductor of heat.
Why is metal not a good insulator of electricity?
Silver is part of the metal group on the Periodic table of elements and metals are good conductors of heat and electricity so silver would be a good conductor and insulator.
Is a fork a conductir or insulator?
If it is made of metal, it is a conductor. If it is wooden, it is an insulator.
How is fabric a good insulator?
because it's not metal
Is modelling clay a good insulator?
Clay is a good insulator because It doesn't have any metal inside, and it's compact.
How is a can a good insulator?
Being made of metal, cans are good conductors, not good insulators.
Is platinum a good insulator?
Platinum is a horrible insulator. Being metal, it conducts heat and electricity quite well.
How do you make a good insulator?
the insulator s metal must has fully filled orbital without any free electron
Is mental a conductor or a insulator?
Metal is a good conductor of electricity and heat.
Is a non metal a good heat insulator?
yes with exceptions like graphite
