What materials conduct heat and which do no?

the materials like metal(which have free electrons) conduct heat and light both and those materials which are formed by covalent bond (do not have free electrons) generaly non metals do not conduct heat and electricity.


What types of materials conduct heat?

Any material that has free electrons.


What are materials with few free electrons called?

such substances are conductors of electricity.


What is the difference between a electrolytic conductor and a metallic conductor?

metalic conductors carries electrical current due to no.of free electrons,electrolytic conductors carries current due to no.of free ions


What does radioactive materials and electricity have in common?

Electrons. Electricity is composed of free electrons and some radioactive decays emit electrons (beta particles)


Why are metallic bonds good conductors for solid?

Metals contain metalic bonds which have free electrons unlike ionic or covalent bonds. As those electrons could flow freely along the metal structure, metals can conduct electricity.


Materials with many free electrons are considered what?

Electrical Conductor


What are bonds in metals like?

In metalic substances metal atoms lose some of their outer shell electrons to make them positive ions (also known as cations). These electrons are then free to move around and as they are negatively charged they hold the positive metal ions together, this is sometimes refered to as a "sea of delocalised electrons", it is also the reason why metals conduct electricity (because electrons are free to move in them)


What statement best describes electrons?

Electron is an elementary particle, negative electrically charged, having a very small mass.


What allows electricity to move through materials?

electricity doesnt move...its the electrons...rather free electrons in materrials that moves nd we call it as electric current


Heat flows easily on what material?

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.


Is a material a good insulator if outer electrons of atoms in the material are free to roam around?

Freely moving electrons make materials more conductive, and less insulating.
