Lakhmir Singh solutions for class 9 chemistry
Chapter 1: Matter and Surroundings
This chapter defines matter and surroundings and the relationship between them. This gives a knowledge of the definition of matter and the classification of matter as solid, liquid and gas and its characteristics like shape, volume and density. It also explains the changes of states melting, freezing evaporation, condensation and sublimation.
Chapter 2: Is Matter Around Us is Pure
In this chapter students will explore elements, compounds and mixtures. The properties of metals, non-metals and metalloids, and differentiation of compounds and mixtures are also explained. Concepts of the solution, suspension and colloids are also briefly discussed. Different methods which involve the separation of mixtures have been explained in this chapter.
Chapter 3: Atoms and Molecules
The chapter deals with atoms and molecules as mentioned in the title. The chapter starts with the Law of combinations which explains three main laws and the experiments performed to verify the laws. The main concept of atoms is illustrated here by taking the very most theory put forth by scientists. Dalton’s concept of an atom has been interestingly explained and explained about the molecules. The concept of atomic mass, molecular mass and gram molecular mass are explained with examples.
Chapter 4: Structure of Atom
In this chapter students will get to know the concept of the structure of an atom. The chapter starts with the story of the discovery of electrons, protons and neutrons and then comes to the various assumptions of scientists for predicting the structure of the atom. The chapter has explained each of the predictions interestingly so the students can grasp the concept without heading down to tedious. The postulates and the drawbacks of each concept are well explained. Then the chapter moves on to explain the arrangement of electrons in an atom and different properties of atoms it possesses.
