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 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
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
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
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 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
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
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
Alfred Walter Steward is the person who for the very first time introduced the term of Isobars. The term has a Greek origin and is composed of two separate words. The first section of the word is “Isos” which means “Equal”, while the second “Baros” means the “Weight”. What are Isobars? Nuclides of atoms that … Read more
