'''Charge''' is the [[fundamental]] property of any [[matter]] that exhibit electrostatic [[attraction]] or repulsion over other matter. Electric charge is a characteristic property of many [http://en.wikipedia.org/wiki/Charged_particle subatomic particles]. The charges of free-standing [[particles]] are integer multiples of the elementary charge e; we say that electric charge is ''quantized''. [http://en.wikipedia.org/wiki/Michael_Faraday Michael Faraday], in his [http://en.wikipedia.org/wiki/Electrolysis electrolysis] [[experiments]], was the first to note the discrete [[nature]] of electric charge. [http://en.wikipedia.org/wiki/Robert_Millikan Robert Millikan]'s oil-drop [[experiment]] [[demonstrated]] this [[fact]] directly, and measured the elementary charge.
