Which scientist is the father of atomic theory?

Answer 1

As is often the case, the East and the West recognize different people as the "father" of a modern field of knowledge.

In the West, John Dalton (1766 - 1844) is generally accepted as the father of modern atomic theory.

In the East, Roger Joseph Boscovich, S.J (1711-1787) is accepted as the father of modern atomic theory.

Of course, about 430 BC the Greek philosopher Democritus said that any one thing was made up of tiny elements of all other things but that it was made up mostly of the elements of the thing they appeared to be. For example, bread was made up tiny elements of water, blood, stone, metal, etc but was mostly made up of tiny bread elements which is why we see it as bread, so the idea has been around a long time.

Answer 2

His name was Leucippus, a Greek philosopher, and a student named Democritus. They first theorized that there must a a tiny particle that could not be broken down and named this particle after their group. However, it wasn't until after Newton's time that this theory was confirmed because Aristotle's theory of elements kept thwarting them.

Answer 3

John Dalton is usually credited as the father of modern atomic theory, although there were various earlier atomic theories proposed by the ancient Greeks and by Roger Boscovich. Dalton's theory was based on the finding that there are integer element ratios in chemical reactions, so it could be used to explain and predict chemical reactions. The earlier theories were more about abstract principles.
