No. Something that is a poor conductor must be a good insulator and vice versa. If a material conducts better than it insulates it is considered a good conductor, if it insulates better than conducts it is considered a good insulator. No material can be both a poor conductor AND a poor insulator. It is impossible.
What else can I help you with?
What are the materials that resist the flow of electric charges through them are called?
Materials that resist the flow of electric charges are called insulators. Insulators have high electrical resistance and do not allow electric current to pass through easily. Some common examples of insulating materials include rubber, glass, and plastic.
True or false does a conductor allow electric current o flow through easily?
Conductors, most metals for example, valence electrons of the atoms can be localized with very little input of energy. Insulators, most non-metals for example on the other hand, offers high resistance to flow electrons through them. In insulators valence electrons of the atoms are tightly bound and therefore at low voltages there is no flow of electrons through them.
What are the differences between charged conductors and insulators?
Insulators block the flow of electricity, and therfore cannot be charged. That is completely wrong. An insulator can be charged. The difference is that the charge carriers in an insulator will be still, and will not respond to each other's fields. This is not true for a conductor, where the coulomb forces between charges will force all charge to the surface of the conductor, as a result of Gauss' law.
Is it true that a material with high resistivity is a good conductor?
No, a material with high resistivity is a poor conductor. Resistivity is a property that quantifies how much a material resists the flow of electric current. Materials with high resistivity impede the flow of current, making them poor conductors.
True or false a good insulator is a poor conductor?
The statement ' a good insulator is a poor conductor' is false because a good insulator will not conduct at all.
True or false leather wood and water are examples of insulators?
Leather, wood, and water are examples of insulators, so this is true.
Does only metals conduct electricity true or false?
False. Metals are good conductors of electricity, but there are other materials such as graphite, saltwater, and some types of solutions that can also conduct electricity.

Is this true or false Nonmetals are good conductors of heat and electricity?
False. Nonmetals are poor conductors of heat and electricity compared to metals. This is because nonmetals have fewer free electrons available to carry an electric current or transfer thermal energy.
Conductors emerging from the ground must be enclosed in approved raceways are true or false?
Conductors emerging from the ground must be enclosed in approved raceways. This is to protect the conductors from becoming damaged and starting a fire.
Hazardous materials are only hazardous to the environment True or False?
False.
Is A mineral is a compound of a metal mixed with other materials on rock true or false?
false. it does not have to have materials from rock :)

True or false When most materials cool they get a little smaller?
It is a true statement.
Is it Metalloids have some characteristics of both metals and nonmetals true or false?
True. Metalloids look like metals but are brittle and are not good conductors.
Japan attacked China and Russia to get raw materials for their economy true or false?
true, they did
