Atomic Theory - Part 1 (FREE)
These notes explore how our understanding of the atom has developed over time, from the earliest ideas to the modern atomic model.
Designed specifically for the new Leaving Certificate Chemistry specification, the focus is not simply on memorising which scientist discovered what. Instead, students will learn to:
- Describe the main models of the atom.
- Explain the assumptions behind each model.
- Discuss the strengths and limitations of each model.
- Understand how new evidence led scientists to refine or replace earlier ideas.
The notes include clear explanations, visual aids and exam-focused questions to help students confidently discuss how scientific models develop as new evidence becomes available.
