In a text about the properties of metals, "Metals are good conductors of heat and electricity." Which of the following is not a property related to this characteristic? A. They have a high density B. They have free electrons C. Their atoms are closely packed D. They are brittle 相关...
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...

Why are metals good conductors, both of heat and electricity? Why is metal a good THERMAL conductor but plastic is a worse conductor than metal? Explain. Good thermal conductors are also good electrical conductors. If so, why don't the connecting wires that are used to connect heaters g...
Answer: Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions....
