Rutherford developed a nuclear model of atom on the basis of his experiment and observations. So the question was, how are the positive and negative particles arranged in an atom. The classic model of an atom was given by ernest rutherford called the rutherford atomic model or rutherford model of the atom. T he model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the sun. It is positively charged and almost all mass of the atom resides in it. This was accurately presented after several scientists came up with different models. Then, on page 12, we consider why the nuclear model was.
One of these thomsons model pictured the atom as a continuous distribution of positive charge and mass with the electrons embedded throughout. The rutherford atomic model has the following features. The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated. It helped solve the problem of the collapsing atom and earned bohr a nobel prize.
The rutherford atomic model has been alternatively called the nuclear. The main points of rutherfords nuclear model are described below. Rutherford model, also called nuclear atom or planetary model of the atom, description of the structure of atoms proposed 1911 by the new zealandborn physicist ernest rutherford. To study such small en tities, ernest rutherford relied on alpha particles. Just as bohr built on rutherfords model, many other. You can imagine this model of the atom as a loosely. Rutherford and the nuclear atom cern document server. Rutherford overturned thomsons model in 1911 with his famous goldfoil experiment, in which he demonstrated that the atom has a tiny, massive nucleus. Then, on page 12, we consider why the nuclear model was successful. This is the model of the atom most commonly portrayed in textbooks. The rutherford model was devised by ernest rutherford to describe an atom. This model predicts a very small amount of scattering at large angles compared to the rutherford theory since the particles traversing this atom rarely see much charge concentrated in a large mass. Electrons spin around the nucleus in a circular path.
