what is radioactivity in chemistry

Radioactivity - 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 matter. In 1896, Henri Becquerel discovered that whe..

All radioactive decays follow first order kinetics. Therefore, the half-life of a radioactive element is independent of the amount of sample. With the help of half-life values of a suitable radioisotope of an element, which is present in a rock, or in an artefact, the age ..

Radioactive elements are those, which emit invisible radiations of their own accord. This is called radioactivity. Some typical examples of radioactive elements are uranium, thorium, plutonium, polonium etc. Radiations emitted by radioactive elements consist..

The spontaneous breaking up of the nucleus is known as radioactive disintegration or radioactive decay. Radioactive disintegration is found to obey the following two laws: i) Atoms of all radioactive elements are undergoing spontaneous disintegration i.e., ar..

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 ..

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 pape..
