Why are nonmetals poor conductors of heat and electricity? Why are nonmetals good insulators? Why are metals good conductors of heat and electricity? Why is a good conductor of electricity also a good conductor of heat? How do insulators help conductors?
I say pure metal because alloys are relatively poor conductors of heat and electricity. This is because alloys are formed by introducing foreign atoms into a metal. This leads to an increase in irregularities, which then obstruct the motion of a free electron. As the free electrons are unable ...
Metals are good conductors of heat since the ions are tightly packed and arranged in a regular pattern.What are bad conductors? Non-metals are generally bad conductors or insulators. The poor conductor has very few numbers of a free electron and will have high resistance to the flow of ...
Notes: Silver is best conductor of heat while among metalsleadis poorest conductor of heat. Who is the poorest conductor of heat? The correct answer isLead. Among metals: Copper & Zinc are good conductors. Mercury metal is a poor conductor while Lead is the poorest conductor. ...

Nonmetals The elements on the right-hand side of the periodic table are thenonmetals. Nonmetals properties are: usually poor conductors of heat and electricity often liquids or gases at room temperature and pressure lack metallic luster readily gain electrons (high electron affinity) ...
Why are ionic solids poor conductors of heat and electricity although they are composed of charged particles? Why don't ionic compounds have electrical conductivity as a solid but they do as a liquid? Describe the characteristic properties of metals, nonmetals, and metalloids. ...

although they lack the classification of a proper metal. While at room temperature, metalloids have poor conductivity. However, when heated, they become relatively good conductors. Adding metals to their structure helps in this regard. Boron, silicon and germanium sit in this designation, and they...
