atomic nucleus energy

Explosive fission reaction is the basic principle of an atom bomb. Two pieces of a fissionable material like U-235 (each with a sub critical mass) are brought together by means of a conventional explosion. The two masses together constitute super critical mass. The chain reaction is star..

. He was awarded the Nobel Prize in 1908. The famous words of Rutherford on completing the alpha rays scattering experiment were: 'It was quite the most incredible event that has ever happened to me in life. It was almost as if you fired a 15 inch shell into a piece of tissue paper and it came back..

As one moves down a group there is increase in nuclear charge. But at the same time the atomic size as well as the number of inner electrons, which shield the valence electrons from the nucleus increase. The overall effect of increase in atomic size and the shielding e..

Relation Between Atomic Number and Atomic Mass - While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic..

While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high atomic mass as well. If you recall from..

Nuclear - Binding energy - The sum of the individual masses of various particle in the nucleus must be equal to the nuclear mass. But this is not so in actual practice. The nuclear mass is somewhat less than the sum of the individual masses of various nuclear particles. The diff..

The Electric Potential Energy - The electric potential energy of the alpha particle at the distance of closest approach from the nucleus was found to be equal to Potential energy x charge on a partic..

In order to explain the stability of an atom Neils Bohr in 1913 proposed a new theory to explain the arrangement of electrons in an atom. According to Neils Bohr, the electrons could revolve around the nucleus only in 'certain orbits' (energy levels), each o..

Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also know that any system that..
