Atoms are the building blocks of all matter. An atom is made up of protons, neutrons and electrons and bond together into stable groups of atoms called 'molecules'.
An electrical charge is a quantity of electrical energy that is held by an object such as a battery. Electric charge can be directly measured with an electrometer.
Electrical conduction is the movement of electrically charged particles due to a force exerted by an electric field. The electric current formed by this movement travels through a conductor.
The acid solution in a vehicle battery is an electrolyte. An electrolyte is a substance that contains free ions and conducts electricity, usually a liquid.
