Why do medals conduct heat and electricity?
Medals conduct heat and electricity because they are typically made of metals, which have loosely bound electrons that can move freely within the material. This allows for the transfer of heat and electricity through the material.
What is it about their atomic structure that enables elements to conduct electricity?
Elements that conduct electricity typically have free electrons in their outer atomic structure. These free electrons are able to move easily through the material, creating an electric current. Metallic elements are good conductors of electricity because they have loosely held outer electrons that are free to move.
The difference between conductor and insulator?
Conductors allow electricity to pass through them easily and insulators don't let electricity pass through easily. Some examples of conductors are most metals and some examples of insulators are wood, rubber, and plastic.
Why are electron in the atom s of conductors easy to knock-off?
Electrons in the outer shells of atoms in conductors, such as metals, are loosely bound to the nucleus due to a relatively low effective nuclear charge and the presence of additional inner electrons that shield the outer electrons. This makes it easier for these valence electrons to gain enough energy to escape from the atomic structure, allowing them to move freely and conduct electricity. Additionally, the metallic bonding in conductors allows for a "sea of electrons" that further facilitates their mobility.
Why are metallic compounds usually good conductors of electricity?
Metallic compounds have a delocalized structure where electrons are free to move throughout the material. These free-moving electrons can easily carry electric charge, making metallic compounds good conductors of electricity.
How does the polarization of insulators and conductors differ in terms of their ability to conduct electricity?
Insulators have tightly bound electrons and do not conduct electricity well, while conductors have loosely bound electrons that can move freely and conduct electricity effectively.

Metallic elements are good conductors of electricity because they have loosely held outer electrons that are free to move.
Does metal reflect?
Yes. Metals have outer electron shells with very loosely attached electrons; this enables metals both to conduct electricity and to reflect photons.
What are the free electrons in a metal called?
Free electrons in a metal are called conduction electrons. These are loosely bound to the metal lattice and are able to move freely throughout the material, allowing metals to conduct electricity efficiently.
How do you know whether a materiel is a conductor or an insulator?
One way to determine if a material is a conductor or an insulator is by testing its ability to conduct electricity. Conductors allow electricity to flow easily through them, while insulators do not. Another method is to consider the material's atomic structure – materials with loosely bound electrons tend to be conductors, while materials with tightly bound electrons tend to be insulators.
What type of materials can conduct electricity?
Materials that can conduct electricity are generally metals and some compounds known as conductors. These materials have loosely held outer electrons that can move freely, allowing electric current to flow through them. Examples include copper, aluminum, gold, and graphite.
Why do solid and liquid metals conduct electricity?
Graphite, an allotrope of carbon, is classified as a semimetal, that is, a material that shares some of the properties of metals. Many other non-metallic materials conduct electricity; including salts, plasma and some polymers.
Why do group 1 and group 2 metals conduct electricity?
Group 1 and Group 2 metals conduct electricity because they have only one or two electrons in their outermost energy level, making it easy for these electrons to move and carry an electric current. The presence of these loosely held electrons allows them to easily flow in response to an electric field.
How conductive is sodium?
Sodium is a moderately conductive metal. It can conduct electricity because it has loosely bound electrons that can move freely. However, it is not as conductive as other metals like copper or silver.
Why can't electricity flow through paper?
Electricity can't flow through paper because paper is an insulator, which means it does not conduct electricity. Insulators like paper have tightly bound electrons that do not move easily, preventing the flow of electric current. Conductors, on the other hand, have loosely bound electrons that can carry electric charge.
How do insulators work and conductors?
Insulators prevent the flow of electricity by having tightly bound outer electrons that do not move easily. Conductors, on the other hand, allow electricity to flow through them easily as they have loosely bound outer electrons that are free to move. This difference in electron mobility is what makes insulators unable to conduct electricity and conductors effective at it.
