How did Democritus and Dalton approaches differ?

How did Democritus and Dalton approaches differ?

The key difference between Democritus and Dalton atomic theory is that the Democritus atomic theory is an ancient theory that scientists later refined and elaborated whereas Dalton atomic theory is a comparatively modern, scientific theory that we cannot discard due its important statements.

What are the differences of the atomic models of Democritus Aristotle and Dalton?

According to Democritus, atoms are solid, homogeneous, and indivisible. Aristotle did not believe in the existence of atoms. John Dalton’s atomic theory is based on numerous scientific experiments.

What is the major difference between Dalton’s theory and modern theory?

Dalton’s says atoms of different elements differ in size and mass, whereas the modern theory says they differ in average mass. Dalton’s says atoms are individual particles, whereas the modern theory says atoms are divisible into subatomic particles like protons, neutrons, and electrons..

What are two ways in which Dalton’s theory is different from our modern understanding of the atom?

According to Dalton’s atomic theory, atoms are indivisible particles. Modern atomic theory says that atoms are composed of subatomic particles; protons, electrons, and neutrons. Dalton’s theory does not explain details about isotopes. It states that all atoms of the same element are identical.

Why is Dalton’s statement of his ideas superior to that of Democritus?

Why is Dalton’s statement of his ideas superior to that of Democritus? Democritus, the philosopher, based his ideas on nothing more than rational thought. Dalton used experimental evidence to support his conclusions. These conclusions have stood up to 200 years of scrutiny.

How were Dalton’s model and Thomson’s model different?

The difference between Dalton’s model of the atom and Thomson’s model was that Dalton’s model had different elements that consist of different atoms and Thomson’s model had atoms that have smaller particles called electrons. Bohr discovered that electrons are arranged in shells or levels around the nucleus.

What was the difference between the Dalton model of the atom and the Rutherford model?

Dalton originally thought that all atoms of a particular element had identical properties, including mass. The Rutherford atom has a small, positively charged nucleus, so most α particles will pass through empty space far from the nucleus and be undeflected.

What is the greatest advantage of Dalton’s atomic theory has over Democritus?

Dalton had an advantage over Democritus – he had some experimental data to back up his ideas. So Dalton could present his thinking with “here is what I believe to be true and here are the experiments that support my theory”.

How is the Democritus atomic theory different from the Dalton atomic theory?

Therefore, the major difference between Democritus and Dalton atomic theory is that the Democritus atomic theory is an ancient theory which scientists later refined and elaborated whereas the Dalton atomic theory is a comparatively modern, scientific theory that we cannot discard due its important statements.

How did Democritus describe the nature of matter?

Democritus atomic theory is the ancient theory that describes the nature of matter in terms of atoms. According to Democritus (99-55 BC), atoms are infinite in number and eternal. We cannot create them, and the composition of atoms in a substance determines the qualities of that substance.

What are the parts of Daltons theory correct?

– compound are made of atoms from multiple elements – chemical reaction is arrangement, separation, and combination of atoms what parts of daltons theory are correct everything made of atoms, compound are made of atoms from multiple elements, chemical reaction is arrangement, separation, and combination of atoms

How did John Dalton describe the nature of matter?

Dalton atomic theory is a modern scientific theory that describes the nature of matter in terms of atoms. With the development of the law of conservation of mass and the law of definite proportions, John Dalton developed a new idea as the law of multiple proportions.
