Who revived the atomic theory and put on a solid experimental foundation in about 1803 by?
John Dalton revived the atomic theory in 1803 by proposing that elements were made up of tiny, indivisible particles called atoms. He also outlined basic principles of atomic theory and provided experimental evidence to support his ideas.
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.
Is the fact that the atom was discovered significant to the agruement that matter is made of atoms?
Yes, the discovery of the atom was significant in supporting the argument that matter is made of atoms. The concept of the atom provided a theoretical foundation to understand the building blocks of matter and how they interact. Additionally, subsequent experimental evidence and advancements in atomic theory further solidified the idea that matter is indeed composed of atoms.
What evidence did Erwin Schrodinger have to support is theory?
When Schrodinger applied his mathematical formulae to the permitted states of an electron in a hydrogen atom, he found they perfectly matched the Bohr Model, which had perfectly predicted hydrogen spectral lines. For Schrondinger, that was good enough for him to publish his work. Max Born later showed that the Schrodinger Equation could be used to accurately predict particle scattering from a nucleus. However, Born showed that this would only work if one assumes that the cross-product of Schrodinger's Wave Function represents the probability of a point charge being in a specific place; something that Schrodinger never accepted.
What was john Dalton's major constraint when he suggested his Atomic Theory?
John Dalton's major constraint when he suggested his Atomic Theory was the lack of experimental evidence at that time to directly support his ideas. He relied mainly on his observations and reasoning, as the technology to directly visualize atoms was not available during his time.

Proposed that matter was made of tiny indivisible particles He called these units atoms He did not have evidence to support his theory?
The proposed individual indivisible particles were atoms, and this idea laid the foundation for modern atomic theory. Although he lacked experimental evidence at the time, subsequent scientific discoveries have validated the existence of atoms as building blocks of matter.
What was a shortcoming of democritus's description of the atom?
Democritus described atoms as indivisible and eternal, which we now know is not entirely true as atoms can be split in nuclear reactions. He also did not provide any empirical evidence to support his theory, unlike modern atomic theory which is based on experimental observations and data.
Which scientist offered proof that atoms exist?
The existence of atoms was proposed by the ancient Greek philosopher Democritus in the 5th century BCE. However, John Dalton provided experimental evidence for the existence of atoms in the early 19th century through his atomic theory, which explained chemical reactions in terms of the combination of atoms.
How did Dalton advance the atomic philosophy propose by democritus?
By using experimental methods Dalton transformed Democritus ideas on atoms into a scientific theory.
Why did it take 2000 years for scientists to confirm some of Democritus ideas about atoms?
Democritus gave a theory, but Aristotle shut him out. Everybody forgot about this, and there was no one looking into this, no progress was being made.
Why was Daltons theory more successful then democritus's theory?
Dalton's theory was more successful than Democritus's theory because of evidence. Evidence existed to support Dalton's theory. While Democritus didn't have any evidence to back up his theory.
What experimental evidence did Thomson have atoms of all elements contain electrons?
The deflection of cathodic rays was the source of inspiration for Thomson.
What experimental evidence did Thomson have for the atoms of all elements contain electrons?
The deflection of cathodic rays was the source of inspiration for Thomson.
The line spectra of atoms provides experimental evidence for?
The line spectra of atoms provide experimental evidence for the quantization of energy levels in atoms. This supports the idea that electrons can only exist in specific energy levels within an atom's electron shells. The specific wavelengths of light emitted or absorbed by atoms in their line spectra confirm the discrete nature of energy levels and the transitions between them.
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.
