Radioactive Decay Law

The law about radioactive decay is a universal law, and it is used for describing the statistical behavior of a large number of nucleoids. The radioactive decay is not a regular process but a random one. It occurs at the level of single atoms, and according to the quantum theory, the prediction about the decay … Read more

Bohr model

Bohr model or Rutherford-Bohr model is a system consisting of a dense nucleus which is surrounded by orbiting electrons it is similar to the structure of the solar system. Though its structure is same like the solar system but it is attracted by electromagnetic force in place of gravity. This model is based on the … Read more

Radioactivity Alpha, Beta and Gamma

Radioactivity Alpha, Beta and Gamma Particles/Rays and Their Properties When the atoms are undergoing radioactivity, then there is the emission of particles like the alpha, beta, and gamma rays. The radioactivity is occurring due to the unstable atoms, which are trying to attain stability. So, when the atoms are unstable, then eventually, they are decaying … Read more

Rutherford’s model of the atom

This experiment is to describe an atom he proposed that an atom is composed of empty space mostly consisting of electrons orbiting in the set around the positively charged nucleus. This comes into the consciousness of everyone after the observations made by Rutherford and those observations are that the major space in an atom is … Read more

Alpha particle scattering material

This experiment is done for finding some conclusions in the world of science and after processing this experiment they found some conclusions, as well as arguments, are also taking place on this particular experiment. They found that most of the alpha particles passed through the coil without suffering and some alpha particles scattered and more … Read more

p-n junction diodes

Special purpose p-n junction diodes: LED, photodiode, solar cell, and Zener diode and their characteristics, Zener diode as a voltage regulator LED: A light-emitting diode (LED) emits visible light when forward biased. Light-emitting diodes are not produced using silicon or on the other hand, germaniums yet are made by utilizing components like gallium, phosphorus, and … Read more

Junction transistor, transistor action, characteristics of a transistor and transistor as an amplifier (common emitter configuration), the basic idea of analog and digital signals, Logic gates (OR, AND, NOT, NAND and NOR) Junction transistor: The bipolar junction transistor (BJT) is worked by three doped semiconductor territories disengaged by two p-n junctions Region, emitter, base, and … Read more

Binding Energy per Nucleon

Binding Energy per Nucleon and its Variation with Mass Number The binding energy per nucleon of the nucleus is the specific binding energy divided by the number of nucleons in total. The nuclei are made up of protons and neutrons but the actual mass of the nucleus is always less as compare to the mass … Read more

Mass Defect

In physics and chemistry, the mass defect is a term referred to the difference in the mass, between the sum of masses of neutrons, protons, electrons of the atoms and mass of atom itself. Typically, the mass defect is associated with a binding energy between the nucleons. The missing mass is the energy that is … Read more

Composition and size of Isotones

We all are familiar with a famous scientist, James Chadwick. He was the scientist who first introduced neutrons, and stated that the mass of neutrons is the same as the protons with little difference in them. Also, he mentioned that the pair of neutron and proton in the nucleus of an atom is called the … Read more
