It is the second book in the series of basic chemistry. First book deals with some elementary concepts like from what the matter around us made up of? Why some substances react and some not? In this book we will try to explore, actually what happens when these substances react? What are the factors which govern these reactions? We shall also perceive the properties of these substances. For our convenience we will categories the substances as acid, base, salt, metal, non-metal and carbon compounds. In the last chapter our emphasis will be at the classification of elements.

This book can be treated as a general course for secondary level students. It includes all fundamental chapters of chemistry. For convenience of study it is divided into two parts. Part 1 includes chapter pertaining to some elementary concepts of ch3emistry, structure of atom, atom and molecules and matter around us. Part 2 includes chemical reactions and equations, acid, bases and salt, metals and non metals, carbon compounds and the last lesson deals with periodic classification of elements.

Necessity is the mother of invention. Human curiosity and imagination had added a wing to our flight of invention. Science has no destination but journey. As a domain of science chemistry also deals with what? Why? How? From what the matter around us made up of? And what are the properties of these matters? These are the subjects of chemistry. It has a golden history from alchemists to the detection of higgs boson (commonly referred by journalists "the god particle"). It is assumed that alchemists used to convert other elements into gold. Now we are observing the same thing only the difference between two elements is the number of fundamental particles electron, proton, and neutrons. Now, we are aware of that the whole universe is made up of 118 elements (discovered till now). Our body, the daily items we use, medicine we take, and our surroundings all are the result of these elements only.

The word electronics is mostly used in day to day life. It is the word which commonly used and rarely understood. This book is just a trial to make a common man familiar with electronics. It is written in such a way to avoid scientific definitions and formulae. It is useful to all whether you have a scientific background or not. If you have a desire to know the basic building blocks of electronics and ready to feel the scope and excitement of electronics, it is the right book for you. It is also very- very useful for all students who are going to opt electronics in their college life. It may be a good start for a pre university student.
