Electricity is not a substance. A substance is composed of atoms, has weight, and inertia. Examples of substances include water, molten cheese, chocolate, hydrogen gas, and bronze, among others.
Electricity is a form of energy. It is a continual stream of electrons, such as that running in a copper wire. Technically, electrons have a very small amount of weight, but are not considered a substance. Electrons are tiny particles, much smaller than atoms, that orbit an atom's nucleus, and carry a negative charge.
