No it doesn't .
Most metals do.
yes, as all it's constituent substances can also conduct electricity
Yes, particularly acidic ones like citrus.
yes gold is a good conducter of heat and electricity
Some common insulators are glass, plastic, rubber, air, and wood.
When external source such as a battery is connected electrons get specific directions to move and condition starts
Plastic does not conduct electricity.
Yes, hydrochloric acid can conduct electricity when it is dissolved in water. In its pure form, hydrochloric acid is a non-conductor of electricity, but when it dissociates into ions in water, it becomes a conductor.
dose carbon dioxide conduct electricty
Sodium Chloride solution (dissolved in water) conducts electricity, and molten Sodium Chloride conducts electricty, but dry crystal Sodium Chloride does not conduct electricity.
Yes, sodium conducts electricity. It is a metal that can easily lose its outer electron to form a positive ion, allowing it to conduct electricity in both solid and molten states.
Plastic does not conduct electricity.
