Electrons move free in the planar, layered structure (graphene) of graphite.
Pencil lead (aka graphite) DOES conduct electricity. It does this thanks to electron delocalization within the carbon layers. Since the valence electrons are free to move, they are able to conduct electricity.
Water contains ions and free electrons that can move and carry electric current, while air is composed mostly of molecules that do not contain free charges. This allows water to conduct electricity, while air does not conduct electricity well due to its lack of free charges.
Each copper atom has lost one electron and become a positive ion. ... The electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons, because they help copper to be a good conductor of heat and electricity. Therefore, copper is an outstanding material to use for conducting electricity! Hope it helped :)
Yes, acid solutions can conduct electricity because they contain ions that are free to move and carry electric charge. The concentration of ions in the solution determines its ability to conduct electricity.
If an object does not conduct electricity, is not shiny, and is not malleable or ductile, it is likely a non-metal. Non-metals are generally poor conductors of heat and electricity, dull in appearance, and brittle. Additionally, non-metals tend to gain electrons when they form compounds.

Metals lose electrons to form cations. These ions help in conducting electricity.

An apple can conduct electricity due to the presence of water and electrolytes inside it, which can help facilitate the flow of electrical current. The ions present in the juice of the apple also contribute to its ability to conduct electricity.
Cotton balls are a better conductor of electricity compared to plastic newspaper because cotton is a natural fiber that contains moisture and minerals, which can help facilitate the flow of electrons. Plastic newspaper, on the other hand, is an insulator and does not conduct electricity well.
Charcoal is an insulator. I had to use charcoal for a lab and see if it was a conductor or insulator, and we found out that it was an insulator since it can't help electrical/heat conductivity. -T :)
Ionic compounds can conduct electricity when dissolved in water because the ions are free to move and carry the electric charge. The water molecules help to separate the ions from each other, allowing them to move and conduct electricity. This is why solutions of ionic compounds are known as electrolytes.

One can identify strong, weak, and nonelectrolytes in a solution by observing their ability to conduct electricity. Strong electrolytes completely dissociate into ions in solution and conduct electricity well. Weak electrolytes partially dissociate and conduct electricity to a lesser extent. Nonelectrolytes do not dissociate into ions and do not conduct electricity. Conductivity testing or knowledge of the compound's chemical properties can help determine the type of electrolyte present in a solution.
