History of the Periodic Table Explained | From Lavoisier to Mendeleev & Henry Moseley

📘 History of Periodic Table | Evolution of Modern Periodic Table Explained
In this detailed lecture, you will learn the complete history and evolution of the periodic table in a simple and easy-to-understand way. This video covers how scientists discovered patterns in elements and developed the modern periodic table we use today.
We start from early attempts of classification like Dobereiner’s Triads, move to Newlands’ Law of Octaves, and then explore Mendeleev’s Periodic Table, which was a major breakthrough in chemistry. Finally, we explain how the Modern Periodic Table is based on atomic number instead of atomic mass.

🎯 What you will learn in this video:
Early classification of elements
Dobereiner’s Triads explained
Newlands’ Law of Octaves
Mendeleev’s periodic table and its achievements
Limitations of Mendeleev’s table
Moseley’s contribution and atomic number concept
Evolution into the modern periodic table
Periods, groups, and trends in the modern table

📊 This lecture is perfect for:
Class 9, 10, 11, 12 students
MDCAT / ECAT preparation
Chemistry beginners
Anyone who wants to understand periodic table basics clearly

💡 Why this topic is important?
The periodic table is the foundation of chemistry. Understanding its evolution helps you learn chemical properties, trends, and element behavior easily.
