After the discovery of electrons and protons it was necessary to know how these particles are arranged within the atom. Various scientists tried to describe this structure and after subsequent improvements through experiments, the structure of an atom is well defined today..

'. The electrons are like plums in a pudding (positive charge). The seeds in a watermelon fruit can be given as a parallel comparison. With this model he tried to explain the observed spectra of elements. According to him, the vibrations of electrons would give rise to electromagnetic ene..

J.J.Thomson proposed the first simple and most primitive model in 1898, which considered an atom to be a sphere of uniform positive charge into which the negatively charged electrons were embedded. This model was like a plum pudding dotted with raisins and w..

J. J Thomson the discoverer of the electron believed that the atom is a uniform sphere of positive charge with electrons (raisins) embedded in it. This model explained the electrical neutrality of atom, but it failed to explain how these fundamental partic..

. In 1793, he left for Manchester to teach physics and chemistry in a college. In 1801, he observed and discovered the law of expansion of gases on heating. He also enunciated the law of partial pressures and found methods of determining vapour pressure of gases. He invented the dew point hygromete..

Summary Atom is the smallest particle of an element, which maintains its identity throughout chemical and physical changes. Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William Crookes and J.J..

Two new theories came to substantially modify Bohr's Atomic model. They a..
