📚 In this lesson, you will learn:

How to understand John Dalton’s Solid Sphere Model of the atom, formulated in 1803, which viewed atoms as indivisible particles.
How to explore JJ Thompson’s discovery of the electron in 1897, leading to the significant shift in understanding atomic structure.
How to describe the Plum Pudding Model proposed by JJ Thompson in 1904, depicting an atom as a positively charged sphere with embedded negatively charged electrons.

✨ Key concepts covered:

Dalton’s Model: Learn the historical notion that atoms were solid spheres without internal structure and why this idea was significant at the time.
Discovery of Electrons: Understand how Thompson’s experiments unveiled the existence of electrons, challenging the indivisibility of atoms.
Plum Pudding Model: Discover how this model illustrated atoms as a mix of positive and negative charges, resembling a pudding with raisins.

🤔 Common Questions Answered:

How did John Dalton describe atoms in his model?
What was the significance of the Plum Pudding Model in atomic theory?
How did JJ Thompson’s discovery of the electron change scientific views on atoms?
How are Dalton's and Thompson’s models different from the modern nuclear model?
Why is it important to understand historical atomic models in physics?

By the end of this lesson, you will have a deeper understanding of how atomic models have evolved and the importance of these early theories in shaping modern atomic science.
