How the atom was proven to exist?

Click For Summary
SUMMARY

The existence of atoms was strongly indicated by early chemistry practices long before the discovery of the electron in 1874. Notably, Antoine Lavoisier's work in the late 18th century laid foundational principles for the Table of Elements, demonstrating that elements combine in fixed ratios to form compounds. The book "Atoms, Molecules and Photons" by Demtröder provides a comprehensive discussion on the scientific basis of atomic theory. This historical context illustrates that the concept of atoms as fundamental building blocks of matter predates modern atomic structure understanding.

PREREQUISITES
  • Understanding of basic chemistry principles, including elements and compounds
  • Familiarity with Lavoisier's contributions to the Table of Elements
  • Knowledge of atomic theory development, particularly Dalton's Atomic Theory
  • Awareness of the historical context of scientific discoveries in the 18th and 19th centuries
NEXT STEPS
  • Read "Atoms, Molecules and Photons" by Demtröder for an in-depth understanding of atomic theory
  • Explore Dalton's Atomic Theory through resources like Khan Academy
  • Investigate the contributions of Antoine Lavoisier to modern chemistry
  • Study the historical progression of atomic structure understanding from the 18th to 20th centuries
USEFUL FOR

Students of chemistry, educators teaching atomic theory, historians of science, and anyone interested in the evolution of scientific thought regarding atomic structure.

How come atom was proven to exist just because the electron was discovered in 1874, atom was like a fad of truth on early 1800s right, where atom was pictured at that time like a small brick of ball and nothing else (no electrons, neutrons, protons, parts, etc) and on that year also, chemistry was brilliantly studied and quantified (w/o knowing electrons, neutrons, etc). how is that, they do chemistry based on elements mass only?

I would say that 'matter' was shown to be based on basic particles long before the confirmation of the existence of the electron. Relatively ancient Chemistry had shown that elements combine in fixed ratios to form compounds. Lavoisier (late 18th century) was well on the way to the basic principles with his early stab at a Table of Elements. Of course, this was far from what was discovered later about the structure of atoms but their 'existence' as building blocks of chemistry was 'strongly indicated' more than two hundred years ago. (Makes one feel quite humble aamof.)
