Ions - atoms with an electrical charge. Actually, pure water is a good insulator, but most naturally-occuring water contains some ions, and will therefore conduct electricity.
A substance that dissolves in solution to conduct an electrical current is an "electrolyte" or, less commonly, an "ionogen".
An insulator is a substance that conducts very little electricity. This is because insulators have high electrical resistance, which prevents the flow of electric current through them. Examples of insulators include rubber, glass, and plastic.
The element is most likely a metal, as metals tend to have good electrical conductivity. The description of a black, dull surface suggests that the metal may not be very shiny or reflective, giving it a dull appearance.
because current was originally reffered to as electrical intensity.
Dry wooden sticks do not conduct electricity because wood is an insulator, meaning it does not allow electrical current to flow through it easily. Conductivity requires the presence of free electrons to carry the charge, which are lacking in wood.
Material with high resistance
It has no (zero) resistance - thus current flows without losses.
Molten sodium hydride conducts electricity because it contains free-moving ions, specifically Na+ and H-. These ions are able to carry an electric charge through the material, allowing for the flow of electrical current.
An electrolyte solution, such as salt water or acid solutions, conducts energy because it contains ions that can carry electric current. When a voltage is applied across the solution, the ions move, allowing the flow of electricity.
Glass is an electrical insulator. But glass more readily conducts heat.

yes actually it is both: 1. it conducts current through the battery from + to - . 2. it transforms chemical energy to electrical energy (current)
Electrons flow because of electrical attraction and repulsion.
The element is most likely a metal, as metals tend to have good electrical conductivity. The description of a black, dull surface suggests that the metal may not be very shiny or reflective, giving it a dull appearance.
An strong acid strongly conducts electricity because contains a large number of ions. Acids can be described as proton donors, or electron acceptors. These ions, when in water, act as charge carriers and can hence conduct electricity (strong electrolytes).
Yes. Any electrical current contains energy.
