In his research, Thomson passed current through a cathode ray tube, similar to the one seen in the Figure below.A cathode ray tube is a glass tube from which virtually all of the air has been removed. It contains a piece of metal called an electrode at each end. One electrode is negatively charged and known as a cathode. WebPostulates of Thomson’s atomic model. Postulate 1: An atom consists of a positively charged sphere with electrons embedded in it. Postulate 2: An atom as a whole is electrically neutral because the negative and positive charges are equal in magnitude. Thomson atomic model is compared to watermelon.
