Models of the Atom: a Historical Perspective John Dalton Early Greek Theories • 400 B.C. - Democritus thought matter could not be divided indefinitely. • This led to the idea of atoms in a void. fire Democritus • 1800 -Dalton proposed a modern atomic model based on experimentation not on pure reason. All matter is made of atoms. Atoms of an element are identical. Each element has different atoms. Atoms of different elements combine in constant ratios to form compounds. • Atoms are rearranged

Chemistry was discovered by a Greek man called Leucippus in the fifth century BC. He came up with the idea that the world was made up of atoms or voids. His student Democritus further refined this idea of the atom and improver the theory so it can make more sense. On the other hand many people did not believe in chemistry and Democritus’ theory. Alchemy‚ it’s a form of chemistry that was studied in the middle ages‚ which was concentrating about trying to change a normal metal into gold. It’s the

when a Greek scholar starting think when can something break on more‚ when are the pieces at their smallest‚ this mans name was Leucippus. Leucippus also had pupil who also thought the same way as Leucippus‚ his name was Democritus. They developed there ideas and when Democritus died his theory summed up briefly was that everything in the world was made of tiny pieced that could not be broken up any more. That how the word atom was derived from the Greek work "atomos" meaning "unbreakable". This

Notions of a similar kind have been hinted at by other Greek thinkers‚ but never so fully elaborated. He states that all matter is composed of

make people question what is right or wrong. People like Leucippus‚ the man who invented the ideas of the atom. Although he could came up with the theory‚ he did not develop the idea. His student‚ Democritus would take this theory and develop them into a true philosophy. In a matter of fact‚ Democritus was considered on the same level of Plato and Aristotle. However‚ he never founded a school‚ which means his ideas was not impactful as Plato and Aristotle in later

first understand atoms how work and how they were discovered. Our journey begins in Ancient Greece during 400 B.C where philosopher Democritus developed the first ever ideas of the atom. He asked what happens if you break a piece of matter in half and then break it in half again‚ how many breaks will you have to make before you cannot break it any further? Democritus thought is eventually had to be unbreakable. He finally concluded that at some point there is the smallest bit of matter and he called

Dalton was the first scientist to help contribute to the atomic theory. He based his thought process off of Democritus‚ an ancient Greek philosopher‚ who stated that at one point you will not be able to break down matter anymore‚ he called this basic building block an atom (meaning not divisible). Democritus believed that everything around us such as metal‚ water‚ and wood were atoms‚ but Dalton believed and proved that it could be more basic than that. He started thinking of compounds such as water

The first person to purpose the existence of atoms was Democritus. Democritus’ had the right idea however the details of his original theory were not quite right. Democritus believed there was a select few elements and the ratio between these elements made up matter. It was free thinking individuals like this that led to the discovery of several theories that aloud
