What is Soddy fajans group displacement law?
The law of radioactive displacement, commonly known as ‘Soddy’s – Fajan’s Displacement Law,’ can be stated as the radioactive element, and the isotope that occurs in each radioactive decay is different for different types of decay. This interchanging of one element to another was called ‘Transmutation of Elements. ‘

Who gave group displacement law?
The fresh and starting element will have the similar atomic number. So by Group displacement law position of the fresh and daughter element in the periodic table will remain as it was earlier. The law which is explained above “Group Displacement Law” was specified in 1913 by Fajan and Soddy.
What is the group displacement law?
Group displacement law states that the emission of alpha or beta particles results in the daughter element occupying a position, in the periodic table, either to the left or right of that of the parent element.
What is rate of disintegration?
For a given element, the decay or disintegration rate is proportional to the number of atoms and the activity measured in terms of atoms per unit time. If “A” represents the disintegration rate and “N” is number of radioactive atoms, then the direct relationship between them can be shown as below: A ∝ N.
What are the laws of radioactive disintegration?
Laws of radioactive disintegration: There is an equal probability for all nuclei of a radioactive element to decay. The rate of spontaneous disintegration of a radioactive element is proportional to the number of nuclei present at that time. N: number of atoms present at time t. λ: decay constant of the element.
What is fajans rule with example?
Fajan’s rule definition in chemistry . It has been experimentally observed that a polar covalent bond is more stable than a pure covalent or a pure ionic bond . The higher the degree of ionic polarization , the greater is the stability of the polar covalent bond .
What is Fajan’s rule Class 11?
The rule says that for cations with same charge and size, the cation with electronic configuration (n−1)dnns0which is found in transition elements have greater covalent character than the cation with electronic configuration ns2np6 which is found in alkali or alkali earth metals.
What is radioactive law?
The radioactive decay law states that “The probability per unit time that a nucleus will decay is a constant, independent of time”. It is represented by λ (lambda) and is called decay constant.
What is artificial transmutation?
Artificial or induced transmutation occurs when atoms of one element are struck with particles in a linear accelerator, cyclotron, or synchrotron. This collision causes the atom to be changed in some way.
