Who did not have experimental evidence to support his theory of the atom?
John Dalton did not have experimental evidence to support his theory of the atom when he first proposed it in the early 19th century. His model was based on a philosophical approach rather than direct experimental observations.
Who is credited with the first atomic theory based on expiramental evidence?
scientific method used in the development of atomic theory
Who was the first scientist generally accredited with putting the study of chemistry on a firm experimental basis?
John Dalton because Dalton predicted new combinations of elements; these new combinations were found providing evidence that Dalton's theory worked.
Why is John Dalton not credited with creating the first theory?
John Dalton is typically not credited with creating the first atomic theory because other scientists before him, such as Democritus and Antoine Lavoisier, had proposed ideas about the atom. Dalton's theory, however, was more comprehensive and backed by experimental evidence, which led to its widespread acceptance in the scientific community.
Who came up with the 4-part atomic theory in 1805?
The first person to develop the first model of the atom in 1803 was John Dalton.
Who was the first scientist to give evidence to support democritus idea about atoms?
Democritus did not do any experiments or provide solid evidence for his theory on the atom. In the 5th century B.C, Democritus proposed an atomic model in which all matter is made up of small indestructible units called atoms.
Why is Dalton credited with proposing the first atomic theory if Democritus was talking about atoms almost 2200 years earlier?
Dalton is credited with proposing the first atomic theory because he provided a systematic and scientific framework for understanding atoms, based on experimental evidence and quantitative measurements. While Democritus introduced the concept of indivisible particles called "atoms," his ideas were philosophical and lacked empirical support. Dalton's theory, formulated in the early 19th century, included key principles such as the law of conservation of mass and the idea that atoms combine in specific ratios, which laid the foundation for modern chemistry.
When did First Battle of Dalton happen?
First Battle of Dalton happened on 1864-02-22.
Although Dalton's atomic theory was rejected at first he used his theory to do what that soon resulted in his theory being accepted by scientists?
Instead of just stating his own personal opinions John Dalton cited evidence to support his atomic theory. The giving of evidence - which could be proved or disproved by others - was what soon resulted in his theory being accepted by scientists.
Who didn't have experimental evidence to support his theory of atoms?
The Greek philosopher Democritus first put forward the idea of atoms as an intellectual theory.
When did Dalton come up with his atomic theory?
John Dalton worked in the first years of the 19th century.
The existence of elements was first discovered by?
Dalton
