The model is named for the resemblance of the atom to a plum pudding, with the electrons in the pudding representing the plum bits.<\/p>\n<p>Thomson&#8217;s model consisted of a positively charged sphere in the center of the atom, with the electrons orbiting around it like planets orbiting around the sun. Thomson did not know what held the electrons in their orbits, but he guessed that it was some sort of force field.<\/p>\n<p>The plum pudding model was eventually replaced by the Rutherford model, which was developed in 1911 by Ernest Rutherford.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Limitations_of_JJ_Thomson_Model_of_Atom_Plum_Pudding_Model\"><\/span>Limitations of JJ Thomson Model of Atom (Plum Pudding Model)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Thomson&#8217;s model of the atom is also called the plum pudding model because of its resemblance to a plum pudding. In this model, the atom is composed of a positively charged, central nucleus surrounded by a negatively charged, electron cloud. Thomson believed that the positive charge of the nucleus was due to the presence of positive particles, which he called corpuscles.<\/p>\n<p>The Thomson model has a number of limitations. One is that it does not account for the structure of the nucleus. Thomson believed that the nucleus was composed of positive particles, but it is now known that the nucleus is composed of protons and neutrons. Another limitation is that the Thomson model does not account for the electron&#8217;s quantum nature. The electron does not have a definite location but instead exists as a probability cloud.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What Do We Understand by Atomic Model?
