The first chapter is matter in our surroundings includes introduction of substance,  physical nature of matter,  characteristics of particles of matter,  classification of matter on the basis of different properties like inter particle spaces,  inter particle forces,  nature,  compressibility,  shape,  volume,  density,  kinetic energy and tendency of diffusion

It covers the inter conversion of matter from one state to other states and different phenomenon and energy terms involved in these processes.

The second chapter includes the detail classification of pure substances and impure substances that is mixture.  

It also includes the detail difference between pure substance and mixture on the basis of nature,  structure,  composition,  properties,  separation of constituents and energy changes. More over this it includes types of solutions and different concentration terms involved in these solutions.Further it has detail difference between true solution,  colloidal solutions and suspensions.It also includes the different techniques for the separation of components of heterogeneous mixture.

 

The third chapter is atoms and molecules which has different laws of chemical combinations,  Dalton's atomic theory,  detail description of elements,  atoms and molecules their chemical symbols, concept of atomicity , atomic mass,  molecular mass and formula mass , writing chemical and molecular formula.
Further is covers the mole concept,  calculations of mole concept in different forms like mass,  particles and volumes in case of gaseous species The fourth chapter is structure of atom which includes discovery of fundamental particles like electron,  proton and neutron, the different atomic models including Thomson's model ,  Rutherford's model and Bohr's atomic model.

More over this it includes concept of shell,  sub shell and orbital , rules for writing electronic configurations, differences in isotopes,  isobars, iso electronic,  isotones.
