Metals are good conductors of heat and electricity because they contain a glut of free electrons. These free electrons are able to move around freely and collide with one another, propagating heat and electricity through the metal. The majority of materials that conduct heat and electricity are m...
No, nonmetals are not good conductors. In fact, nonmetals are so bad at conducting heat and electricity that they are classified as insulators... See full answer below. Learn more about this topic: Nonmetal Elements | Definition, Properties & Examples from...
Metals are good conductors (both of heat and electricity) becauseat least one electron per atom is free: i.e., it is not tied to any particular atom, but is, instead, able to move freely throughout the metal. Why are metals good conductors of electricity and glass is not?
