Explain how developments made in the understanding of the atomic model changed from Bohr till Quantum model

Starting from discovery of electron, then gold foil experiment, Bohr model and then de Broglie and Heisenberg principle have played a vital role in the development of Quantum model of atomic structure. Explain how developments made in the understanding of the atomic model changed from Bohr till Quantum model?

3. Prior to quantum mechanics the Bohr Model viewed the atom as having electrons traveling in circular orbits (shells) about the positively charged nucleus. This model gives a reasonable estimate of the dipole moment of the hydrogen atom if one assumes the radius of the electron orbit about the nucleus is 5.3 x 10-11 m. Using the Bohr Model (a) what is the dipole moment of the hydrogen atom? Now place the hydrogen atom in a magnetic field, B, with...
