Question

what are the limitations of Rutherford's model of an atom ?

Answer 1

it explained the atom on the classical concepts. he proposed that electrons revolve around the nucleus. but now according to quantum model of atom, it is considered that we can't find the position and velocity of electron simultaneously(heisenberg principle) therefore only the volumes in which there is about 99%probability of finding the electron are considered known as orbitals.

Answer 2

1. Rutherford's model can not explain the
discontinuous nature of of H-spectrum.
2 he could not explain that an electron is a changed particle moving around the nucleus, it it must also emit energy continuously and if it thus , so then it can not maintain radius of its path and it will ultimately full into the nucleus following a spiral path .there by making the atom unstable.
