Why is silicon a good heat conductor but a poor electrical conductor?
Metals are actually good conductors of both heat and electricity... but silicon is a semi-conductor. Unlike metals, which are good electrical and heat conductors, crystalline solids such as diamond and semiconductors such as silicon are good heat conductors but poor electrical conductors. This is their nature... you can't change it :-)
Is it true that nonmetals are good conductors of heat and electricity?
Some nonmetallic materials are good conductors, graphite being an example. In this form, it is considered a semi-metal for that reason. Normally, however, nonmetals are not good electrical conductors.
Is ionic solutions poor conductors of electricity?
(in short) No, whilst in their solid state ionic crystals are very poor conductors of electricity, however when molten or dissolved their ions are able to carry charge, therefore they are very good conductors of electricity when molten or dissolved in e.g. water. Pure water is a very poor electrical conductor too, it's the dissolved ions that carry the charge.
Why are weak acids and weak bases poor electrical conductors?
They only give free very small amounts of H+ (from acid) or OH- (from base anions).
How do you account for fair and poor conductors of electricity?
The mobility of the electrons in matter. Tightly bound electrons make for poor conductors.
What does an electrical insulator have?
Electrical insulators are made from materials that are poor conductors of electricity. Metallic elements are good conductors, non metallic elements are poor conductors. Some materials used as insulators are, paper, glass, ceramics, rubber and plastics.
Are all elements good electrical conductors?
No. Non-metals are very poor conductors, and with the exception of Neon, so are the gaseous elements.
What are a few poor electrical conductors?
If by "poor" you mean that reluctantly carries a small charge, that you may want a resistor. A resistor is an electrical device that reduces the voltage of a current.
What type of elements would not be a good choice for use in electrical wiring?
Nonmetals would not work because they are poor conductors of electricity

What are the classification of materials according to electrical conductivity?
Most substances fall into two categories - conductors and insulators. Conductors are those which electricity can pass through relatively easily. Metals are the usual example, but other substances such as graphite and polar liquids such as water are also good conductors. Insulators are poor conductors: those that electricity cannot pass through easily. Most plastics are insulators. Some substances fall in between: these are semiconductors, which allow electricity through in some instances, but not in others. This property makes them very useful in electronics. Some substances can be such good conductors that, under some circumstances, they can allow electricity to pass through them with no resistance at all. These are called superconductors.
What are non metals?
They are non mental substances such as Oxygen, Mercury, Xenon, and others. They are poor conductors of heat and electricity, not lustorous (shiny), and are brittle. This description is in general, there are exceptions.
Are poor conductors of heat poor conductors of electricity?
Yes.
Are metals poor conductors of electricity?
No, metals are good conductors of electricity due to the presence of free-flowing electrons in their atomic structure. These electrons are able to carry electrical charge through the metal efficiently.
Is it true that nonmetals are good conductors of heat and electricity?
Some nonmetallic materials are good conductors, graphite being an example. In this form, it is considered a semi-metal for that reason. Normally, however, nonmetals are not good electrical conductors.

Pure water is a very poor electrical conductor too, it's the dissolved ions that carry the charge.
Materials that are poor conductors of heat?
Materials that are poor conductors of heat are Plastic and Wood "example."
