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....
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 of electricity? Sulfur deposits are mined by the Frasch process. Explain why free sulfur is not found on the earth's surface. Why does electroplating take place on the cathode a...
Is amorphous glass (SiO2) a good conductor? Why or why not? Lead is a poor electrical conductor. Use chemistry to explain why it is a poor conductor. Why do metals conduct heat and electricity? Why are ionic solids poor conductors of heat and electr...
why She knows why the metal is the good conductor. 她知道金属为什么是好的导体。 Must you dash off? Why not stay for a cup of tea? 你一定要急急忙忙走吗?为何不留下喝杯茶呢? Is that why you don't want to go home? 这就是你不想回家的原因吗? That explains why she is not here. ...
Which metals conduct the best?Above: Electron shells Gold (au), Silver (Ag), Copper(Cu) and Zinc (Zn). Logic would have one think that Gold is the best conductor having a single s-orbital electron in the last shell (above chart) ... so why are Silver and Copper actually better (...
Why?It’s because metals conduct electricity. And you would get a terrible shock!【小题4】Can you think why?It’s because water is a good conductor of electricity. When your hands are wet or when your body is in a bathtub full of water, the electricity could flo...
