How Did We Develop Early Models of the Atom?

In my studies, I find myself coming back to the same question.How do we know all these things about matter. Its quantized, it has mass and, charge and blah blah blah. I understand that these models of the building blocks of "physical things" are well tested mathematical models that attempt to make sense of the data we have about material interactions and also make sense of thousands of experiments that were designed to test the limit of the applicability of the model at that time.
But where can I find some actual, well laid out explanations about the history of the development of the model? I'm going to be doing modern physics next semester which I'm being told is more so a study of the tools needed to talk about the quantum model than the actual development towards the quantum model. My electricity and magnetism class is building tools to discuss point charge interactions without discussing any of the evidence for the attractive\repulsive point charge model. I want my evidence darn it!
So I ask you well read contributed, do you know of any good material on the historical development of the introductory mathematical models of matter we use as physicists?

A nice and easy to follow introduction can be found in the book Atoms, Molecules and Photons by Demtröder (Springer), which has a chapter on "The Concept of the Atom."

Very cool. I like the look of this book. Thank you Drclaude.

Malcolm Longair has a chapter in his book Theoretical Concepts in Physics, discussing black body radiation which led Planck to introduce h-bar. Planck's arguments span Electromagnetics, Statitsical Mechanics and Thermodynamics and really show how physics is one whole-ness rather than a collection of different disciplines. It is good reading

I understand your curiosity about the historical development of the models we use to understand matter. It is important to have a solid understanding of the foundations of these models in order to fully grasp their implications and limitations.

The history of the development of the pre-modern atom can be traced back to ancient Greek philosophers such as Democritus and Aristotle, who first proposed the idea of atoms as indivisible building blocks of matter. However, it was not until the 19th century that scientists began to develop more detailed models of the atom.

One of the key figures in the development of the pre-modern atom was John Dalton, who proposed the atomic theory in the early 1800s. This theory stated that all matter is composed of small, indivisible particles called atoms, and that these atoms combine in specific ratios to form compounds. This model was later refined by J.J. Thomson, who discovered the electron and proposed the plum pudding model of the atom.

The next major advancement in our understanding of the atom came from Ernest Rutherford, who performed the famous gold foil experiment and proposed the nuclear model of the atom. This model suggested that the atom consists of a small, dense nucleus surrounded by orbiting electrons.

In the early 20th century, Niels Bohr further developed the nuclear model by proposing that electrons exist in specific energy levels around the nucleus, and can only transition between these levels by absorbing or emitting energy. This led to the development of the Bohr model of the atom, which was the first to incorporate quantum mechanics.

The development of quantum mechanics in the early 20th century revolutionized our understanding of the atom and led to the creation of more advanced models such as the Schrödinger model and the quantum mechanical model. These models incorporate the concept of wave-particle duality and explain the behavior of subatomic particles in terms of probability.

In terms of resources, there are many books and articles that discuss the history of the development of the pre-modern atom. Some recommended readings include "The History of the Atom" by John Dalton and "The Atom and the Apple: 12 Tales from Contemporary Physics" by Sébastien Balibar. Additionally, many universities offer courses on the history of physics or the history of the atom, which may be helpful in gaining a deeper understanding of the subject.

In conclusion, the development of our understanding of the atom has been a long and complex journey, with contributions from many scientists over centuries
