The number of atoms disintegrated per second at any instant is directly proportional to the number of radioactive atoms actually present in the sample at that instant. If N o be the total number of atoms at t = 0, N be the total number of atoms left in the sample at time t then ..

A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or elemen..

Rate of Disintegration - Suppose an element A disintegrates into another element B. Let number of atoms of A when t = 0 is N 0 . A undergoes continuous disintegration into B and hence the number of atoms of A goes on decreasing. Let the number of atoms of A left undisi..

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 et..

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 externa..

Rate of Radioactive Decay - 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 radioact..

. It has changed into an atom of another substance which may be unstable (will undergo further disintegration) or stable (will not emit any more particles), it is not possible to control this change. Neither is it possible to reverse it. Changing the temperature, changes the rate at which..

The spontaneous breaking up of the nucleus is known as radioactive disintegration or radioactive deca..

Radioactive Decay Series - 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 produ..
