Answer 1

Atoms n molecules is the important chapter for your basic chemistry..
you have to face problems while solving the valency of the molecule and then u have to learn atleast the 20 atomic numbers of atoms line wise..then the molar mass, atomic mass, mole concept and avocado number...
mainly in this chapter you have to learn the definition for atoms and molecules then how to calculate atomic mass and molecular mass , then the mole concept and valencies...
