Assignment physics Electric charge Electric charge , basic property of  matter  carried by some elementary particles. Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed . Many fundamental, or subatomic, particles of matter have the property of  electric charge . For  example ,   Electrons have negative  charge   Protons have positive  charge , but Neutrons have zero  charge History of charge: In the 18th century , Ø Benjamin Franklin   in America tried experiments with  charges . It was Franklin who named the two kinds of electricity 'positive' and 'negative' . He even collected electric  charges  from thunderstorm clouds through wet string from a kite. Ø Franklin was an advocate of a ‘single fluid’ model of electric charge. An object with an excess of fluid would have one charge; an object with a deficit of fluid...
