What is the Thomson's, Rutherford's & Bohr's Atomic Model theory?
We can explain, atom structure from these atomic model theories ( 1) Thomson's Atomic Model - J.J.Thomson gave the first idea regarding structure of atom. According to this model. • An atom is a solid sphere in which entire & positive charge. It's mass is uniformly distributed in which negative charge (electron) are embedded like seeds in watermelon. • This model explained successfully the phenomenon of thermionic emission, ionisation & photoelectric emission. Failure of Thomson's Atomic Model - • Thomson's atomic model fail to explain the scattering of alfa - particles & it can't explain the origin of spectral lines observed in the spectrum of hydrogen & other atom. ( 2) Rutherford's Atomic Model - Rutherford's atomic model bassed on alfa - particles scattering experiment. • Most of the mass & all of the charge af on atom concentrated in a very small region is called atomic nucleus. • Nucleus is ...
