Match List-I with List-II and select the correct answer given below:a)...
The electron was discovered in 1896, by the British physicist J. J. Thomson, using cathode rays while doing discharge tube experiments. In 1886, Eugen Goldstein discovered the existence of a new type of rays in discharge tube and named as anode rays or canal rays. Canal or anode rays travel in straight line and are deflected by electric field towards cathode which proves that they are composed of positively charged particles. These lightest positively charged particles were named and characterised as protons by Ernest Rutherford in 1919 who purposed Rutherford model for atom to explain the atomic structure. Anti-electron or in other words the positron was discovered in 1932 by Anderson, a physicists and he found that the bombardment of boron with an alpha particle resulted in the emission of this particle. In 1932, James Chadwick, an English physicist who had worked with Rutherford, detected neutrons.
