disadvantages of radioactive isotopes atoms

The phenomenon of spontaneous disintegration of an unstable nucleus of naturally occurring isotope accompanied by emission of active radiations line a , b and g radiations is known as Natural Radioactivity. These radiations come from the breakup of the central core or nucl..

These are the elements having same atomic number but different mass number. They have the same atomic number because the number of protons inside their nuclei remains the same. The difference in their mass number is due to the difference in their number of neutrons. Since they ..

Isotopes are the different forms of the same element, which have the same atomic number but different mass numbers. The isotopes of hydrogen are protium, deuterium and tritium with mass number 1, 2 and 3 respectively. The relative abundance of three isotopes..

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 isotopes of the same element have the same number of protons, but a variable number of neutrons. The isotopes of hydrogen have the following structures (Fig.9.1)...
