Democritus, a pre-Socratic philosopher, proposed that atoms are indivisible and eternal particles that make up all matter, emphasizing their qualitative differences based on shape and size. In contrast, John Dalton, in the early 19th century, formulated a more scientific atomic theory, asserting that atoms are indivisible spheres and that each element consists of identical atoms with a specific mass. Dalton also introduced the concept of chemical compounds formed by combinations of different atoms, laying the groundwork for modern chemistry. While both viewed atoms as fundamental units of matter, Dalton's model was more systematic and aligned with empirical evidence.
What else can I help you with?
Atomic theory was a result of a proposal by?
The Greek philosophers Leucippus and Democritus
What is Dalton's model of an atom described as?
Dalton's theory was based on the principal that the atoms of different elements that could be distinguished by differences in their weights. In 1803, at the Royal Institution He stated this theory.
Who did people think is correct Democritus or John Dalton?
In the early 19th century, John Dalton's atomic theory gained widespread acceptance over Democritus's earlier ideas. While Democritus proposed that matter was composed of indivisible atoms, his ideas lacked experimental evidence and were largely philosophical. Dalton built on Democritus's concepts but provided a scientific framework supported by empirical data, making his theory more credible among scientists of his time. Ultimately, Dalton's work laid the foundation for modern chemistry, leading to greater acceptance of his ideas over those of Democritus.
Who proposed the first atomic theory in 400 BC?
john Dalton
What are similarities or differences between the ancient Greek philosophers Leucippus and Democritus concept of the atom and Dalton's atomic theory?
The early philisophers (Leukippus and Democritus) 2500 years ago couldnt prove that atoms existed, and people had not discovered the study of matter yet. The idea of Greeks was genial but is only a philosophical suppostion, only that.Dalton combined the idea of elements with the earlier history of the atom, and the chemical and physical knowledge from 1800.
How was Dalton's atomic theory similar to democritus's atomic theory?
They both thought the same theory but Dalton had evidence to prove it, unlike Democritus.
Who used experiments to and scientific tools to study matter John Dalton Aristotle or Democritus?
John Dalton used experiments and scientific tools to study matter. Aristotle and Democritus did not use such methods in their studies of matter.
Who discovered atom before John Dalton?
democritus
Was Dalton the first scientist to study matter?
no Democritus
How did Dalton advance the atomic philosophy propose by democritus?
By using experimental methods Dalton transformed Democritus ideas on atoms into a scientific theory.
Who described atoms that they are small hard particles?
John Dalton. N.B.: John Dalton [born: September 6, 1776; died: July 27, 1844, at age 67] was an English chemist and physicist who claimed matter was made up of tiny particles and that these particles were identical for any given kind of matter. Moreover, he claimed these particles were indivisible and could neither be created nor destroyed in any chemical process, only be altered in the manner they were grouped.
What is the relationship between Democritus and Dalton's atomic theory?
Democritus, an ancient Greek philosopher, first proposed the idea of atoms as indivisible particles. Dalton's atomic theory, developed in the 19th century, expanded on this concept by introducing the idea of atoms combining in specific ratios to form compounds. Dalton's theory built upon and refined Democritus' original idea of atoms, laying the foundation for modern atomic theory.
What are the term used by democritus to identify the particles of an element?
The term used by Democritus to identify the particles of an element is atomic theory. It was thought up by John Dalton between the years 1766 and 1844.
Did Democritus describe that Atoms are small hard particles?
Yes, Democritus described that atoms are small, indivisible, and indestructible particles that make up all matter. He believed that atoms are constantly moving and combining to form different substances.
Atomic theory was a result of a proposal by?

What is Dalton's model of an atom described as?
