An insulator is the general term for things that do not conduct electricity. Rubber is a good example. Glass, paper and Teflon are also other good examples of insulators. It is too broad to point out a specific type. I would have been inclined to say a polymer, (i.e. plastics) but conducting polymers have very popular use as conductors.
yes there are substances that do not conduct electricity when dissolved in water. molecular substances like sugar.
nonelectrolites
gases
These are the ionic substances.
These substances are ionic compounds forming electrolytes by dissociation in water.
Yes, ionic compounds can only conduct electricity when molten or dissolved.
When an ionic compound dissolves in water there are free ions which move and carry electric current.
In solid state the ions are packed very tightly, so ions are not free to move, therefore no conduction.
an electrolyte
These are the ionic substances.
because of the gravity or Magnetricity
because when the ions can move around freely, they can conduct electricity better
The product of a metal reacting with a nonmetal is a salt; in solid form these do not conduct electricity well, but dissolved in water they do.
These substances are ionic compounds forming electrolytes by dissociation in water.
Yes, ionic compounds can only conduct electricity when molten or dissolved.
When an ionic compound dissolves in water there are free ions which move and carry electric current.
i don't know ( In the book )
Some do. Electrolytes, which are substances that break into ions when dissolved in water, will conduct electricity. Such substances include soluble salts, acids, and bases.Other water soluble substances are non electrolytes and do not break into ions in water, or at least do so in extremely minute amounts. They do not conduct electricity. These include alcohols, sugars, and some other polar compounds.
metalloids
Yes, it will conduct electric current much better than plain water. The sugar molecules in water form a clear solution by ionization facilitating the path of electrons of electric current.
