Question

What was the main difference between Dalton's model of the atom and the model that was first developed by the Greeks?

Answer 1

I know that Dalton's model was a hard sphere that was the same throughout, something like a tiny marble; but what was the Greek model?

Answer 2

The greeks proposed that all matter was made up of 4 elemental substances - earth, water, air and fire. One of the famous proponents of this idea was Aristotle. A few, however, posited the question whether matter is continuous and infinitely divisible into smaller pieces or composed of small indivisible particles. Known proponents of this idea, which gave rise to the word "atoms" were Demokritos of Abdera and Leucippos.

Since there were no experiments made to disprove any claims, no definitive conclusion were ever made. And since Since Aristotle was the bomb diggity at the time, people believed him more than Demokritos. The idea that matter composed of 4 elemental particles pretty much became the common knowledge until 17th CE.

Answer 3

Do you need Dalton's Atomic Theory? There are four things to remember when referring to his works.

Answer 5

Thank you! Everything you said was quite helpful; I appreciate all your efforts. :)
But what would you say was the MAIN difference? The fact that the Greek theories were the results of reasoning, debating, and discussion, rather than evidence or proof; whereas Dalton's theory was based on experimental data and had more proof which helped it make sense?
