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?
English chemist and physicist John Dalton was the first scientist to provide experimental evidence supporting Democritus' idea of atoms. In 1803, Dalton published his atomic theory, which proposed that elements are made up of tiny, indivisible particles called atoms that combine in simple whole-number ratios to form compounds.
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?
Erwin Schrödinger developed his theory of wave mechanics to explain the behavior of electrons in atoms. His theory was supported by the successful explanation of the spectrum of hydrogen atoms and the ability to calculate various properties of atoms based on the wave function. Additionally, experimental evidence, such as diffraction patterns of electrons, provided support for his wave-particle duality concept.
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.
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.
How did Dalton advance the atomic philosophy propose by democritus?
By using experimental methods Dalton transformed Democritus ideas on atoms into a scientific theory.
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.
What experimental evidence did Thomson have 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.
