Mass defect and binding energy Mass Defect: In the context of physics and nuclear chemistry, mass defect refers to the difference in mass between an atomic nucleus and the sum of its individual protons and neutrons (nucleons). It is a…
Radioactive decay Unstable atomic nuclei lose energy and convert into more stable nuclei through a process known as radioactive decay. During this process, radiation in the form of particles or electromagnetic waves is frequently released. This phenomenon occurs in particular types…

X-rays production and spectrum The modern X-ray tube, called as Coolidge X-rays tube, was designed by Dr. Coolidge in 1916, has vacuum inside it. Discovery of X-rays: The discovery of X-rays is an important milestone in the field of physics…
Atomic nucleus The composition of an atomic nucleus has been the subject of controversy since a long time. The idea of an atomic nucleus came into existence after an experiment by Rutherford on the scattering of alpha particles from a…
Spectra and their types Spectra, in the context of physics and chemistry, refers to the distribution of electromagnetic radiation (light) emitted or absorbed by a substance as they are separated or dispersed according to their frequencies or wavelengths. The study…
Rutherford’s Atom model It furnishes an important insight into the structure of an atom in congruence with some practical observations. Rutherford’s alpha Particles Scattering Experiment As an attempt to investigate the structure of the atom, Rutherford along with his two…
Bohr’s atom model This atom model accounts for the stability of the atom and the line spectrum exhibited by the hydrogen atom. Consequent upon the failure of Rutherford’s atomic model to explain the stability of the atom and the line…
Electron microscope It is an opto-electronic device having extremely higher resolving power in comparison to that of an optical microscope. De-Broglie hypothesis had been the key factor that led to the development of new branch of optics in Physics called…
