Q.How is Bohr's Atomic Model different from Rutherford's Model of Atom? Explain.

Rutherford's nuclear model, built directly on the Geiger-Marsden scattering results, places essentially the entire positive charge and 99.9% of an atom's mass into an extremely small, dense central nucleus (about $10^{-5}$ times the size of the whole atom), around which the much lighter electrons revolve in orbits -- much as planets orbit the Sun under gravity. This picture correctly explains why most alpha particles pass through a thin foil almost undeflected (travelling through mostly empty space between the nucleus and the electron orbits) while a rare few, passing very close to a nucleus, are scattered through large angles by its concentrated charge. …
