About the Book

Preface

We are pleased to present A New Approach to I.C.S.E. Chemistry for Class IX, written strictly in accordance with the latest syllabus prescribed by the Council for the Indian School Certificate Examinations (CISCE), New Delhi.

The book is carefully divided into five distinct parts, each designed to build a strong conceptual foundation in Chemistry:

1. Part I – The Language of Chemistry, Chemical Changes and Reactions, and Water introduce students to the diversity of matter.

2. Part II – Atomic Structure and Chemical Bonding, and The Periodic Table emphasize the underlying unity in matter and explain the rules governing chemical interactions.

3. Part III – Study of the First Element – Hydrogen and Study of Gas Laws familiarize students with the chemical properties of hydrogen and the behavior of gases under varying conditions of temperature and pressure.

4. Part IV – Focuses on Atmospheric Pollution, highlighting environmental concerns and chemical contributions.

5. Part V – Dedicated to Practical Chemistry, aiding students in laboratory preparation and hands-on learning.

Salient features of this book include:

• Numerous chemical reactions explained with clear experimental observations.

• Key points and definitions highlighted for quick reference and clarity.

• Simple, informative diagrams that support better conceptual understanding.

• A new approach introduced in The Language of Chemistry chapter for balancing chemical equations based on atomic numbers—a fundamental and logical method.

• A dedicated chapter on Practical Chemistry to enhance lab-related skills and knowledge.

• Competency-Focused Practice Questions (CFPQ) provided chapter-wise to develop problem-solving abilities and practical understanding.

• Chapter-wise Question Bank for revision and reinforcement, with solutions accessible via QR Codes.

• A Periodic Table showcasing atomic numbers, mass numbers, and correct nomenclature of elements.

• A Solved Specimen Paper and Model Test Papers 1 to 5 (Unsolved) provided through QR Codes for self-assessment and practice.

We trust this book will serve as a valuable resource for both students and teachers, supporting effective learning and academic success in Chemistry.

We warmly welcome constructive feedback and suggestions to improve future editions of this book.
