Our idea of the atom has changed over time as new experimental evidence and theoretical advances have been made. Early models were based on limited information and as technology improved, we discovered more about the structure of the atom. Each new model built upon the shortcomings of the previous one, leading to our current understanding based on quantum mechanics.
The Billiard Ball Model is John Dalton's idea of what an atom looks like.
I have no idea been searching myself cant find the answer :(
At first we didn't now that the atom existed. It was Einstein who discovered that pollen grains were moving in a glass of water. Why? It was because as he later confirmed that the water particles were pushing it in an unbalanced way. Other scientists later discovered that there are protons, neutrons and electrons in an atom.

Its RADIOACTIVITY!! That was the first discovery that rejects the idea that the atom is indestructible
Democritus from Abdera
Robert Boyle
No device can give the complete structure of an atom but you can get a minute idea about the look of an atom using an Electron Microscope!
need a picture of ruthersford idea of what an atom looked like

Democritus
The idea of the atom was first developed by Greek philosophers Leucippus and Democritus in 5th century BC. Their idea was overlooked until Antoine Lavoisier's experiments were done in the 18th century.
