charged particles proton

The rays that deflected towards the negative plate consist of positively charged particles and these were called alpha rays. The rays, which deflected towards the positive plate, consist of negatively charged particles and these rays were known as the be..

Electric Charges and Field - The word 'electric' is derived from the Greek word 'elektron' meaning amber. The existence of charges were known when charged particles were produced by rubbing (due to friction) of suitable materials. These facts are demonstrated..

Question: a) Which atom contains only two fundamental particles? b) Which particle has constant charge to mass ratio for all matter? Answer: a) The hydrogen atom contains only two fundamental particles. b) Cathode ray particles i.e., ele..

During radioactive emissions, the product formed as a result of the emission of an a - particle followed by the emission of two b - particles is an isotope of the parent elemen..

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. Q..

Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William Crookes and J.J. Thomson led to the discovery of electro..

Models of Atom - J.J Thomson's and Rutherford's Models - 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 experime..

Since most of the alpha particles pass straight through the gold foil without any deflection it shows there is a lot of empty space in an atom. Some of the alpha particles are deflected through small and large angles, which shows that there is a 'centre of positive cha..

Keeping the prevailing model in mind (Thomson's 'raisin pudding') the cloud of positive electricity should offer little resistance to the passage of alpha particle even though the latter is charged. The reasoning is that alpha particles are moving at high speed and ha..
