radioactivity reactions

. It has changed into an atom of another substance which may be unstable (will undergo further disintegration) or stable (will not emit any more particles), it is not possible to control this change. Neither is it possible to reverse it. Changing the temperature, changes the rate at which a chemica..

Radioactivity is broadly classified into two categories: a) Natural radioactivity and b) Artificial or Induced radioactivity..

. Nowadays other bombarding particles (i.e., projectiles) like protons ( 1 H 1 ), deutrons 1 H 2 electrons can be accelerated to very high speeds by fluctuating electric and magnetic fields in machines such as cyclotron, synchrotron etc. These high speed particles are more efficient in causing nucl..

Protons and neutrons Nuclear forces Electromagnetic repulsion between the protons Nuclear fusion and fission reactions Radioactive isotopes Three most common forms of radioactive decay (alpha, beta, gamma) Changes in the nucleus in each type of decay Alpha..

Nuclear energy is the energy released when certain changes take place in the nucleus of an atom. Nuclear energy is partly renewable and partly non-renewable source of energy. Nuclear fission and nuclear fusion are the two types of reactions that release nuclear energy: a) Nuclear fusion -..

Rutherford's alpha particle scattering experiment explained the structure of atom and the size of nucleus. The Bohr's model explained the hydrogen spectrum. Radioactivity occurs due to nuclei being unstable resulting in the emission of three types of radiations having different properties..

. After this no change in concentration occurs provided the temperature of the reaction mixture is kept constant. Thus at equilibrium the reaction does not stop but the system acquires constant observable properties because of the equal rates of forward and backward reactio..

'. The electrons are like plums in a pudding (positive charge). The seeds in a watermelon fruit can be given as a parallel comparison. With this model he tried to explain the observed spectra of elements. According to him, the vibrations of electrons would give rise to electromagnetic energy radiat..
