Web24 feb. 2012 · At the time of discovery, J.J. Thomson called this negatively charged particle a corpuscles. Thomson’s Plum Pudding Model is the first model to represent the atomic structure of matter. According to Thomson’s Plum Pudding Model, a substance is consists of small spheres which are having the radius of about 10 -10 m in diameter. Thomson discovered this through his explorations on the properties of cathode rays. Thomson made his suggestion on 30 April 1897 following his discovery that cathode rays (at the time known as Lenard rays) could travel much further through air than expected for an atom-sized particle.
