  Defect of Bohr's atomic model A). Based on contradictory theory. This theory is based on two opposing theories such Defect of Bohr's atomic model as law of classical mechanics and quantum theory. Bohr applied the classical mechanics to describe the electionic motions in atoms. Bohrs retained the essential spirit of Rutherford's atomic model which is based on classical mechanics on the other hand, the quantization of angular momentum of electron is based on quantum mechanics, b). Applicable for uni-electronic system only. This theory is applicable only for uni- electronic chemical species but not for multi- electronic chemical species for example: this theory is applicable for hydrogen of hydrogen like species such as He+ , Li++ . c. Unable to explain the fine structure of spectra: when hydrogen specrta are observed through powerful spectroscope for single spectra line of the ordinary hydrogen spectrum, several closely spaced line lines are observed. Bohr's atomic mo...

In this post we have talked about "Bohr's atomic model "defect of Bohr's atomic model , disadvantage of Bohr's atomic model which is most essential part of chemistry of class-11 and 12 which is important for the student of class-11 . We have posted note copy photo and paste pdf of it for class-11 student . Defect of Bohr's atomic model a. Based on contradictory theory: This theory is based on two opposing theories such as law of classical mechanics and quantum theory.

  IT is a salware that works as an interface between a user and the computer hardware. The primary objective of an operating systernis to make computer system convenient to use and lo ulilize computer hardware in an cicient manner. The operating system performs the basic tasks such as rebot Notes pdf ing input from the keyboard, processing instructions and sending output to the screen We'll be covering the following topics in this tutorial: 🔴What is Operating System 🔴Functions of operating system 🔴 Different type of operating system 🔴How Operating System Work 🔴Characteristics of Operating System What is Operating System The Sottware is the Non-Touchable Parts of the Computer and Softwares are those which are used for Performing an Operation so That Software are just used for Making an Application but hardware's are those which are used for performing an Operation Note copy pdf https://photos.app.goo.gl/ZeiTKJMwFMY9UvYw6 Computer note pdf nerating system software that is re...

  Elasticity Marcas certain mass and occupies some space. A matter can exist in three state solid, liquid Waste properties and liquid state of matter accounts for surface tension and viscosity while the ange. Each state of matter has some distinct properties. For example, the solid state of matter has keudes. These atoms and molecules hold each other with a force. The force which is responsible to dus state of mutter accounts for pressure, diffusion etc. A matter is made up of atoms and bell the acamus together is called interakonic force and the force responsible to bind the molecules of matter is called intermolecular force. A expression for energy stored in a stretched wire is derived. Finally, related problems both students will get knowledge about young modulus, bulk modulus, shear modulus and Poisson's ratio. Numerical and conceptual are solved in the text as examples and for practice, they are given in the as which enable the students to solve the problems related to this ch...

Scroll down for pdf of thermodynamics  Thermodynamics THERMAL EXPANSION • The increase in shape and size of a material on heating is known as thermal expansion • As the temperature of a material increases, molecules occupy greater space and hence their intermolecular space increases and so, the body gets expanded. . As the temperature of a material decreases, molecules come closer and hence their intermolecular space decreases and so, the body gets contracted. • Thermal expansion is minimum in solids,more in liquids and maximum in gases because intermolecular forces. • Solid _______ > length, area and volume Liquid and gas___________> volume                 Solid expansion The increase in shape and size of a solid on heating is known as solid expansion. Solids have all three kinds of thermal expansions. - Linear expansion - Superficial expansion - Cubical expansion Linear Expansion • The increase in length of solid on heating is known a...
