Almost all good conductors of electricity known to man are metals or alloys. The problem of using exposed metal as conductors in electronics is that they tend to oxidize rather rapidly. Oxidized metals then go on to become poor conductors of electricity. One...
Which of the following are good conductors of electricity in the molten state? View Solution Mica is a good conductor of electricity. View Solution Is boron a good conductor of electricity ? View Solution Dry air is a good conductor of electricity. ...
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 me...
Because metals have large numbers of nonlocalized electrons.
Why are metals good conductors of electricity? Why are a solution of copper sulfate and sulfuric acid required in corrosion testing? Why does zinc decompose when reacted with copper sulfate? Why is iron more reactive than copper? Explain why the copper element has two ion charges. Expla...
Step-by-Step Solution:1. Understanding Conductors and Insulators: - Conductors are materials that allow electricity to flow through them easily, while insulators do not. To determine whether a substance is a
