Modern science relies on inorganic chemistry in materials science, catalysis, environmental chemistry, and bioinorganic systems. Inorganic Chemistry aims to introduce the fundamental concepts, principles, and applications of this crucial field in a comprehensive and approachable manner. This book targets undergraduate and graduate students, educators, and researchers. It covers ancient and modern inorganic chemistry. The chapters progress from atomic structure, bonding, and periodic patterns to coordination chemistry, organometallics, and bioinorganic chemistry. This book aims to bridge theory and practice. Each chapter includes thorough explanations, examples, and problem sets to promote critical thinking and knowledge application. Inorganic chemistry's significance and impact on daily life and industry are shown through real-world applications throughout the work. This book is the result of much research, teaching, and passion for the subject. It seeks to teach, as well as spark curiosity and enthusiasm for inorganic chemistry's complexity. we hope readers find this book instructive and engaging and useful in their academic and professional careers. Many colleagues, students, and the scientific community helped me write this work. Their feedback helped shape this work's content and approach. I thank them deeply. We believe this book will help readers appreciate inorganic chemistry and inspire future chemists to explore its unlimited potential.
