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 :(
democritus
Its RADIOACTIVITY!! That was the first discovery that rejects the idea that the atom is indestructible
Democritus from Abdera
Robert Boyle
Democritus did not have experimental evidence to support his idea of the atom. Instead, his idea was based on philosophical reasoning and speculation.
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!

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.
John Dalton put forward the idea that each element is made of a different sort of atom. Each kind of atom had its own properties such as an individual mass.
