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.
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.
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.
The Greek philosopher Democritus first proposed the idea of the existence of atoms around 400 B.C. His ideas are the cornerstone of which modern scientific theory?
Democritus's idea of atoms laid the groundwork for the modern atomic theory, which posits that matter is composed of discrete units called atoms. This theory has been fundamental in the development of chemistry and physics, explaining the behavior and interactions of matter at the molecular level. His concept of indivisible particles was later refined by scientists such as John Dalton and has been validated through extensive experimental evidence.
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.

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 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.
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.
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.
