The Greek philosophers Leucippus and Democritus
john Dalton
He pubish is own atomic theory in 1803 developed his atomic theory by observations gathered from many experiments .
In the early 19th century, John Dalton's atomic theory gained widespread acceptance over Democritus's earlier ideas. While Democritus proposed that matter was composed of indivisible atoms, his ideas lacked experimental evidence and were largely philosophical. Dalton built on Democritus's concepts but provided a scientific framework supported by empirical data, making his theory more credible among scientists of his time. Ultimately, Dalton's work laid the foundation for modern chemistry, leading to greater acceptance of his ideas over those of Democritus.
Democritus' atomic theory was largely philosophical and lacked empirical evidence, making it difficult for the scientific community of his time to accept. In contrast, John Dalton's atomic theory was grounded in experimental observations and provided a systematic framework for understanding chemical reactions, including the law of multiple proportions. Dalton's work also integrated quantitative measurements, which appealed to the emerging scientific methods of the 19th century, leading to broader acceptance of his ideas. As a result, Dalton's theory laid the foundation for modern chemistry, whereas Democritus' concepts remained largely speculative.
They both thought the same theory but Dalton had evidence to prove it, unlike Democritus.
By using experimental methods Dalton transformed Democritus ideas on atoms into a scientific theory.
The Greek philosophers Leucippus and Democritus
john Dalton
Democritus, an ancient Greek philosopher, first proposed the idea of atoms as indivisible particles. Dalton's atomic theory, developed in the 19th century, expanded on this concept by introducing the idea of atoms combining in specific ratios to form compounds. Dalton's theory built upon and refined Democritus' original idea of atoms, laying the foundation for modern atomic theory.
They both proposed the theory that all matter consists of atoms.
By using experimental methods Dalton transformed Democritus ideas on atoms into a scientific theory.
Leukippus, Democritus, Dalton, Bohr, Rutherford, Thomson and many others.
Both Dalton and Democritus proposed that matter is made up of indivisible particles called atoms that are different in size and shape. They also believed that atoms are in constant motion and can combine to form different substances.
