In the previous article, we talked about how J.J. Thompson disproved Dalton's Atomic Theory. In this article, we will discuss the discovery of the nucleus by Rutherford. The beams are reflected and bent due to the nucleus. The beam is an alpha particle beam. credit The Gold Foil experiment was conducted by emitting alpha particle beams towards a gold foil. Most of the alpha particles from the beam passed…

Thompson discovered the presence of subatomic atoms called electrons, disproving the theory that all atoms are indivisible. His model of atomic structure was known as the Plum Pudding Model (look carefully - it actually does look kind of like a plum colored pudding). The yellow circles…
