within two years, by Henry Moseley. Even though mercedes GLS inre dimensioner it was largely accepted, it still carries certain drawbacks and limitations. The main difference between Bohr model and Rutherford model is that in Rutherford model, electrons can revolve in any orbit around the nucleus, whereas in Bohr model, electrons can revolve in a definite shell. Basic diagram of the atomic nuclear model: electrons in green and nucleus in red 3D animation of an atom incorporating the Rutherford model.

Rutherfords model states that most of the atom consists of an empty space and the center of the atom contains a positively charged nucleus surrounded by negatively charged electrons, resulting in continuous electron spectrum. Plum pudding atom (Public Domain) via Commons Wikimedia. Overview and Key Difference. These are the key indicators- The atom's electron cloud does not influence alpha particle scattering. This region would be known as the " nucleus " of the atom. Distance of Closest Approach ro 1 /. Electrons were found to be even smaller. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure. On the basis of this experiment, Rutherford made following observations (i) The entire positive charge and almost entire mass of the atom is concentrated at its centre in a very tiny moske göteborg ramberget region of the order of 10-15 m, called nucleus.
