alpha rays and beta rays

Emission of a and b -rays bring some changes in the nucleus of the atom and the new element formed as a result of these charges is called daughter elemen..

Cathode Rays - When the pressure in the discharge tube is less than 10 - 4 mm of Hg, the discharge tube starts showing fluorescence. When this fluorescence was investigated, it was found that the fluorescence consisted of beams of negatively charged electrons. These electrons emanate norm..

When the pressure in the discharge tube is less than 10 - 4 mm of Hg, the discharge tube starts showing fluorescence. When this fluorescence was investigated, it was found that the fluorescence consisted of beams of negatively charged electrons. These electrons emanate normally from the cathode. As..

Alpha rays consist of stream of positively charged particles carrying charge of +2 units and a mass of four units on the atomic weight scale (i.e., 4 amu). They consist of 2 protons and 2 neutrons. In other words, these particles are helium nuclei and therefore indicated as 2..
