Why are metals good conductors of electricity and glass is not? Metals are good conductor of electricity as they havelow resistivity and they have free electrons. Glass is a bad conductor of electricity as it has high resistivity and have no free electrons. ...
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...

Explain the purpose of a salt bridge in an electrochemical cell. Why are metals good conductors of electricity? Explain the role of acids in promoting corrosion. Explain why some electrolyte solutions are strongly conducting, whereas others are weakly conducting. ...
When electrons travel, do they produce and/or carry electricity? Why are metals good conductors of electric current? a. They possess high concentrations of protons. b. They possess low concentrations of protons. c. They possess high concentrations of free electrons ...
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...
Why is copper (II) sulfate solution a good conductor of electricity? Why are metals good conductors of electricity? How can you know when a molecule is a semi-insulator? Is it only metalloids? Explain. Why does cold metal conduct electricity better than...
The structures of pure metals are simple to describe since the atoms that form these metals can be thought of as identical perfect spheres. More specifically the metallic structure consists of 'aligned positive ions' (cations) in a "sea" of delocalized electrons. This means that the electrons ...
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 flow ri...
The reasons why he did it are obscure. 1 他做那事的理由还不清楚。 I couldn't cipher out why she was there. 我搞不清她为什么会在那儿。 That is why electricity finds such a wide application in industry. 那就是为什么电在工业上得到这样广泛应用的原因。 I don't know why she is hostile ...
