WebApr 7, 2024 · "Ernest Rutherford," a British physicist, proposed a model of atomic structure known as Rutherford's Model of Atoms. He conducted an experiment in which he bombarded -particles in a thin gold sheet. He investigated the trajectory of the -particles after interaction with the thin sheet of gold in this experiment. WebJun 3, 2024 · Limitation: In Rutherford’s atomic model , Nucleus & electrons are held together by electrostatic force of attraction which would lead to the fusion between them. This does not happen in the atom. Atomic radius ~ 100 pm = 1 x 10−10−10 m Nuclear radius ~ 5 x 10−3−3 pm=5×10−15m5×10−15m
