∙ 13y agoEssentially nil; like many other ancient Greeks, he was talking out his hat and coincidentally happened to come up with something that's not entirely unrelated to what we now know to be true.
In the case of Empedocles, it was the suggestion that all matter might be made of combinations of a few types of basic substances. He got the number wrong, he got the substances wrong, he got the forces wrong, and he tried to work in mythology somehow, but in a sense it's the basis for the notion of elements (though he didn't use that term).

John Dalton first pursued research into atomic theory. He was the first person to propose the existence of the atomic structure.
What was Lord Rutherford contribution to Science Department?

john dalton developed the atomic theory , which he published in 1803
When was Empedocles born?
He was born 495 BC

That the cake is a lie.
Who was empedocles how did he develop his theorywho was empedocles how did he develop his theorywho was empedocles how did he develop his theorywho was empedocles how did he develop his theory?
Empedocles was a Greek philosopher who lived from 490 to 430 BC. He is most well known for claiming the existence of only four elements: earth, fire, air and water. He developed this theory in response to a popular philosophical argument over change in the natural world.
What was Lavoisier's contributions to the development of the modern atomic theory?
Antoine Lavoisier was a French nobleman and chemist. His contribution to the development of the modern atomic theory was his idea of the possibility of an Atomic Mass.
What was Werner Heinsberg's contribution to the atomic theory?
The most important contribution of Werner Heisenberg was the discovery of the uncertainty principle.
What was Antoine-laurent lavoiser's contribution to atomic theory?
he contributed by creating milk
What was the main contribution of de Broglie to atomic theory?
See the link below
What is the contribution of thales of miletus in the development of atomic theory?
The contribution of anyone prior to about 1600 to the development of atomic theory might as well be "nothing whatsoever." Democritus and/or Leucippus contributed the name "atomos", but not much else; they were wrong about nearly every detail. John Dalton is just about the earliest scientist to have had any significant contribution to atomic theory, and most of what we now consider atomic theory was developed since about 1900.
What was lavoisiers greatest contribution to science?
His atomic theory. He was the one who thought that there were atoms in everything.
Michael Faraday contribution on the atomic theory?
he helped the creator of electrons and the studier of chemistry
What De broiglie contribution in atomic theory?
He proposed the wave-particle duality for the electrons.
