In 1896, the phenomenon of radioactivity was accidentally discovered by French scientist Henri Becquerel. He was performing experiments with uranium compounds. He accidentally placed a crystal of potassium uranyl sulphate over photographic plate wrapped with usual black paper. On develo..

It is a nuclear phenomenon. It is due to the instability of the nucleus. It is a spontaneous, continuous and irreversible process. It is independent of external factors such as pressure, temperature, state of substance, electrical field, magnetic field, catalyst etc. A radioactiv..

There are a small number of radioisotopes of low proton number, which occur naturally. They are produced by bombardment by radiation from outer space (cosmic rays). The most well known of these is radioactive carbon-14, which is produced when nitrogen is bombarded by neutron..

.e., polonium, radium, etc., which were more active than uranium. These substances, which have the property of spontaneous emission of radiation are called radioactive substances and the process of spontaneous emission of radiation is called Radioactivity. It was later found tha..

The discovery of the electron towards the end of the nineteenth century was the starting point of new avenues of research in science, which were to give physicists an insight into the structure and nature of the atoms of matte..

The emission of a or b - particles from a radioactive element results in the function of new element called daughter element. If the daughter element still has unstable nucleus, it further disintegrates by emitting a or b - particle and produces a new daughter element. This process of suc..

. 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 reactions. Thus the equilibrium ..
