Today I studied Chapter 2, 3 & 4 of TMH IIT JEE study guide.
In the second chapter, liquids section there is discussion of surface tension and viscocity.
In the solids section, there is discussion on crystalline structure of solids.
In the third chapter on Atomic Structure, the four quantum numbers are given. One of the principles says that no two electrons in an atom will have all the four quantum numbers same.
In the fourth chapter, on periodicity, it is mostly the material that was covered in the x class. Revising x portion is very important for a quick understanding of XI and XII material.
