Abstract

As late as 1895 physicists and chemists seemed to be convinced that the ultimate particles of matter consist of atoms which cannot be further broken down. In 1896, a new phenomenon, i.e., radioactivity, was discovered by Henri Becquerel (1852- 1908) of France, which changed our ideas regarding the ultimate particles of matter. The discovery of X-rays by Prof. Roentgen (1845-1923) in 1895, of cathode rays by J. Plucker (1801-1868) and others also helped in modifying the scientists’ notion regarding the atom.
