With Aristotle and the ancient Greeks.
Democritus achievements are his atomic theory and his book -on the little order of the world- which describes his atomic theory.
The ancient Greeks did not perform any experiments to test the atomic theory proposed by Democritus. To the ancient Greeks the atomic theory was a part of philosophy, not science.
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
the atomic bomb was not discovered, it was invented then built.
They never heard of this theory.
It began with Democritus, who lived in ancient Greece. He didnt study atoms, but he did concept the idea of them
Lavoisier is not known for an atomic theory.
when i was atomic theory i was a smart
Atomic theory was founded by John Dalton. He proved this theory in 1803.
he did not develop anything regarding the 'atomic theory' for he was against that theory.
They didn't help with atomic theory, they created it.
John Dalton first pursued research into atomic theory. He was the first person to propose the existence of the atomic structure.
He pubish is own atomic theory in 1803 developed his atomic theory by observations gathered from many experiments .
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
The Atomic Theory
They both thought the same theory but Dalton had evidence to prove it, unlike Democritus.
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
