They only give free very small amounts of H+ (from acid) or OH- (from base anions).

Are acidic solutions good or poor conductors of electricity?
Strong acids in solution are better conductors than weak acids in solution, and both are better than pure water.
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 covalent-network substances poor electrical conductors?
There is generally a lack of free electrons to conduct electricty. For example diamond (an allotrope of carbon) and silicon dioxide, which are very poor conductors. . Some network covalent t are semiconductors- like silicon- which mean that they can conduct but poorly.
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 acidic solutions good or poor conductors of electricity?
Strong acids in solution are better conductors than weak acids in solution, and both are better than pure water.
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 do you think about acids and bases?
I think acids donate electrons and bases accept electrons. Both acid and bases can be weak or strong, that is good or poor electrolytes. What else is there to think?
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

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.

Materials that are poor conductors of heat?
Materials that are poor conductors of heat are Plastic and Wood "example."
