Ashish Gehlot

hello guys,
This is Ashish and this is my 9th course on unacademy platform. This is chapter 4 from class 9th science NCERT named structure of an atom. In this course we have 8 lessons starting from introduction to chapter till summary of the chapter. In this course we will talk about Proton, electron, neutron and its discoveries. We will also talk about failure of Dalton theory and structure of atom. 3 models of an atom were given by scientist. Thomson's model, Rutherford's model and Bohr's model. We will briefly talk about it. We will also talk about valency and in the last theory segment will talk about atomic number mass number isotopes and isobars. We will also have a question bank with containing 20 MCQs and at the end we will finish this chapter with a lesson on summary of the chapter. Please follow me and rate, review, recommend this course to your fellows. 
Thank you
