The course explains everything about the atom and its structure. The course explains the discovery of subatomic particles and their organization within an atom. Later, we discuss that how their number and arrangement affect the properties and characteristics of an atom. After going through this course, one will be able to get depth knowledge of this Atom Structure unit of Chemistry and will also be able to score good marks in the examination. Tags: Class 9 NCERT, Structure of Atom, Electrons, Protons, Neutrons, Class 9 CBSE Students, Class 9 ICSE Students.

This lesson provides an overview of what topics will be covered in the course and how the course will help you score better.

Overview of the Course

In this lesson, we discuss what are atoms and subatomic particles. The lesson explains the cathode ray experiment and the characteristics of electrons.

Electrons

This lesson explains how protons and neutrons were discovered. In the lesson, the characteristics of protons and neutrons are also discussed. In the end, Thomson Model of Atom has also been explained in the lesson.

Protons and Neutrons

This lesson explains the Rutherford Experiment and the Rutherford Model of Atom.

Rutherford's Model of Atom

This lesson explains the Bohr's Model of Atom and atomic number and mass number.

Bohr's Model of Atom

This lesson explains how the electrons are arranged in various energy shells of the atom and how this arrangement affects the chemical properties of the atom.

Electronic Configuration of Elements

This lesson explains why do atoms combine and take part in chemical reactions. This lesson explains valency in detail. In the end , the lesson also explains everything about noble gases.

Valency

This lesson deals with the isotopes and isobars in great detail. The lesson also explains how to calculate the fractional atomic masses of elements.

Isotopes

Shreya Agarwal

This course is designed for students preparing for IIT JEE examinations and for those in class 9 CBSE board. It has a detailed discussion on Atoms and Molecules. The topics that I am covering in this course are Laws of Chemical Combination, Dalton's atomic theory, Atoms, atomic mass. Also I am helping you learn about molecules and ions. Last but not the least there is a topic involving the chemical formulae of the compounds followed by a Summary of the course.

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
