Rutherford proposed that electrons revolve at high speed in circular orbits around the positively charged nucleus. But according to the electromagnetic theory, if a charged particle were accelerated around another charged particle then there would be a continuous radiation of energy. Th..

(i) Every atom consists of a nucleus containing the entire +ve charge. The whole mass of atom is concentrated at this core. (ii) The size of the nucleus i.e., 10 - 1 5 m is very small compared to the size of the atom (i.e., 10 - 1 0 m). (iii) The atom..

A stream of alpha particles (much like a stream of tiny bullets) was directed at a thin foil of gold atoms and a detector arranged to surround the sample completely except for a small hole for entry of the particles. The foil was several thousands of atoms thick...

After the discovery of the radioactive particles, Rutherford performed an experiment where he bombarded a thin sheet of gold with a particles obtained from a radioactive substance. On striking the gold foil some of the a particles scattered and produced flashes on a zinc sulphide (Zn..

On the basis of the scattering experiment, Rutherford described the structure of the atom as: An atom consists of a positively charged nucleus surrounded by electrons that move around it. The positive charge of the nucleus is due to the protons. Electrons and neu..

Ernest Rutherford, an energetic Scientist From New Zealand working in England, was studying the properties of particles spontaneously emitted by radioactive substances. Of particular interest was a positively charged, relatively heavy emission named alpha particle. Quantities of such pa..

The atom of an element consists of a small, positively charged nucleus in the centre, which carries almost the entire mass of the atom. The electrons are revolving around the nucleus at high speed. The number of electrons in an atom is equal to the number of protons..

Rutherford proposed that electrons revolve at high speed in circular orbits around the positively charged nucleus. But according to the electromagnetic theory, if a charged particle were accelerated around another charged particle then there would be a continuous radiation of energy. Th..

After the discovery of electrons and protons it was necessary to know how these particles are arranged within the atom. Various scientists tried to describe this structure and after subsequent improvements through experiments, the structure of an atom is well defined today..

. In it, he pictured a sphere of positive charges mixed together with an equal number of electrons. For his theoretical and experimental investigations into the electron and the conduction of electricity by gases he was awarded the 1906 Noble prize in Physics. He and his student Rutherford..
