uses of radioactive isotopes atoms

All isotopes of a substance have the same chemical properties and behave in an identical manner. The advantage of a radioisotope is that its position can be detected very easily by the radiation which it emits. It has wide applications in various fields lik..

Isotopes are atoms of the same element having different atomic mass but same atomic number. For e.g., there are three isotopes of hydrogen with atomic mass 1, 2, and 3. According to Mendeleev's periodic table these should be placed at thr..

It is interesting to note that atoms of a given atomic number can have different number of neutrons. Some examples are listed belo..

Atoms of the same element having the same atomic number but different mass numbers are called isotopes. The nuclei of these atoms have same number of protons but different number of neutrons. All the properties of the isotopes depending upon m..

Isotopes of an element have same atomic number (Z) but different mass numbers (A). For example, 1 H 1 , 1 H 2 , 1 H 3 are isotopes of hydrogen;..

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..

.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..

It is a spontaneous emission or disintegration of an unstable nucleus resulting in certain radiations. The elements exhibiting this phenomena are called radioactive elements. e.g., radium, thorium, actinium, polonium etc. Radioactivity does not occur due to any external provocat..

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 of the..
