Isobars and Isomers Isobars: Those atoms which have the same atomic weight or mass number but atomic numbers are different, they are called isobars. So,…

Isotopes: Atoms of an element having a same atomic number but different atomic masses are called isotopes. They are atoms that have the same number…

Mean Life or average life of a Radioactive Element We know, radioactivity is a spontaneous phenomenon. It obeys the exponential law and the life of…

The half-life of a Radioactive Element The half-life of a radioactive element is defined as the time during which the number of atoms remaining unchanged…

Radioactive Decay Law Radioactivity is a spontaneous and continuous phenomenon. By the continuous emission of radioactive radiations, a radioactive element is converted into another radioactive…

Radioactive Decay After three years of the discovery of radioactivity scientists Elster and Geitel observed that the radioactivity of a body decreases with time, it…

Properties Radioactive of Gamma–Rays (γ-rays) We know, from radioactive substances three types of rays are emitted. These are α, β, and y-rays. Gamma–Rays are a…

Properties of Radioactive Beta-rays (β-rays) We know, from radioactive substances three types of rays are emitted. These are α, β, and y-rays. A beta particle…

We know, from radioactive substances three types of rays are emitted. These are α, β, and y-rays. Here Alpha-rays (α-rays) properties are described below. Their different…

Radioactive Rays In 1899, Rutherford and Willard, in course of the analysis of radioactive radiations found that there were three types of rays in radioactive…
