Good insulators contain materials with high resistance to the flow of heat or electricity, such as rubber, plastic, glass, wood, and ceramic. These materials have tightly packed molecules that do not allow heat or electricity to pass through easily, making them effective insulators.

What elements are good insulators?
Materials with high electrical resistance, such as rubber, glass, and plastic, are good insulators. Non-metals like wood and ceramic also have insulating properties. Additionally, gases like air and vacuum can act as insulators due to their low thermal conductivity.
Are halogens good insulators?
Halogens, a group of chemicals that include elements like chlorine and fluorine, are not good insulators. In fact, many halogens are highly reactive and can conduct electricity. Their properties make them more suitable for use in electrical components or chemical reactions rather than as insulators.
What elements are good insulators Li and Ca?
Both lithium (Li) and calcium (Ca) are not good insulators. They are metals that are more likely to conduct electricity due to the presence of mobile electrons in their atomic structure. Instead, materials like rubber, glass, and plastic are examples of good insulators due to their high resistance to the flow of electricity.
A characteristic of most nonmetallic solids is that they are?
they are NOT good conductors of heat and they are brittle solids.
What elements are the best insulators?
Non-metals (e.g. sulphur) are usually good insulators, with the exception of carbon in the form of graphite. On the other hand, metals are good conductors of electricity in all states of matter.
Why are plastic good electricity insulators?
Plastics are a good electrical insulators because they are insulators. Electricity could not pass through them unlike copper. Another good example of insulators is rubber.
Do good insulators contain trapped air?
Yes, good insulators often contain pockets of air trapped within their structure. Air is a poor conductor of heat, so having trapped air helps to minimize heat transfer through the material, making it an effective insulator. This is why materials like wool, fiberglass, and Styrofoam, which contain trapped air, are commonly used as insulation.
What kinds of materials make good insulators?
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
What are some good insulators?
plastic, paper, wood, cardboard, and rubber are all good insulators
Why is an insulator never a good conductor?
Insulators contain very few free electrons to carry electric current, which makes them poor conductors. Their atomic structure does not allow for the easy flow of electrons like conductors, resulting in higher resistance to the passage of electricity.
Are diapers good insulators?
diapers are good insulators because they hold in the cold and and heat but is a bad conductor
What are some good insulators for a thermos?

Are insulators Gasoline engines and diesel engines?
no, insulators protect the wiring, or contain heat from some source or another, or block electricity from flowing
Is shiny a good insulator?
No, shiny surfaces are not good insulators. Shiny surfaces are reflective and do not support the absorption and retention of heat, which is a characteristic of good insulators. Good insulators are materials with low thermal conductivity that trap heat effectively.
What is the name of materials that are not good conductors of electricity?
They are called insulators. Rubber is an example of a good electrical insulator.More:PlasticGlassAirWoodCeramicPorcelainPaperVarnishMineral OilSlateMarblePolyethyleneSiliconePVCKaptonTeflon
