Bohr's Atomic Model, Bohr's - Sommerfeld Atomic Model, Quantum Mechanical Model | Structure of Atom Class 10 | Part 3 You can watch the video before going to read the article about Bohr's atomic model, Bohr-Sommerfeld atomic model, Quantum mechanical modal.   What the main postulates of the Bohr's atomic Model of a Hydrogen atom? Main Postulates of Bohr's Model of a Hydrogen Atom: The following are the main postulates of the Neils Bohr's Atomic model of a Hydrogen atom, Electrons in an atom occupy stationary orbits (energy levels) of fixed energy at different distances from the center called the nucleus. When an electron jumps from a lower energy state to a higher energy state, it absorbs energy and emits energy when such a jump occurs from a higher energy level (state) to lower energy level (state). The energy of an electron in an atom can have only certain values E1, E2, E3,... i.e. the energy is quantized. The states corresponding to these energies are called...

Structure of Atom: 10th Physics Sub-atomic particle: Electron Proton  Neutron Fundamental Atomic models: J.J Thomson Earnest Rutherford Neils Bohr What is Spectrum? Spectrum: A series of coloured bands separated and arranger in an order of their respective wavelengths. (or) A spectrum is a group of wavelengths. Example: Visible Spectrum (VIBGYOR) VIBGYOR V - Violet, I- Indigo, B- Blue, G - Green, Y - Yellow, O - Orange, R - Red Intensity: The amount of force or energy of heat, light, sound etc. Visible Spectrum: The range of wavelengths covering red colour to violet colour is called the visible spectrum. Red colour       -  High wavelength,    Low frequency Violet Colour   -  Low Wavelength,    High frequency Wave:  A regularly repeated disturbance or displacement in a medium like air, water. Wave nature of light: Electromagnetic waves are produced when an electric charge vibrates (moves back and forth). for example, Visible li...
