The Nucleus
The Nucleus - Rutherford and his co-workers, performed series of scattering experiments and concluded that the entire mass and the positive charge is concentrated in a very small region at the centre of the atom, known as nucleus. The radius of the nucleus is..
Atomic Nucleus
Atomic Nucleus - It is the central core of the atom where the entire +ve charge and mass is concentrated. It is a tiny sphere of diameter ranging from 10 - 1 5 m to 10 - 1 4 m. A nucleus is made up of particles called neutrons and protons. A neutron does not ..

Why electron cannot exist in the nucleus?
On the basis of Heisenberg's uncertainty principle, it can be shown as to why electron cannot exist within the atomic nucleus. The radius of the atomic nucleus is of the order of 10 - 1 5 m. Now, if the electron were to exist within the nucleus, the..
Rutherford's model - discovery of nucleus
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 particles ar..
Atomic Hydrogen
Langmuir ,in 1915, obtained atomic hydrogen by dissociating on a hot filament of tungsten or platinum. The dissociation of molecular hydrogen is an endothermic process. The atomic hydrogen is stable only for a fraction of a second and immediately..
