Aristotle: 384-322 B . C .
Aristotle’s theory made a great generalization off all matter being made from the four things: fire, water, globe, and air. He also believed that there are four qualities in order to these elements: dryness, hotness, coldness, as well as moistness. Based on these kinds of beliefs fire would hold the characteristics of getting dry and hot, water is damp and cold, oxygen is hot as well as wet, while planet earth is dry as well as cold.
Democritus: Traditional era 350 B . C .
He was the initial to use the word atom and proposed that atoms were mechanically bound. It seemed to him that in the event that atoms stayed together they made it happen with a system as being a hook and eyes. While we know that this isn't true, he was very far in front of his time through acknowledging the existence from the atom and lots of people consider him the daddy of modern technology for his contributions.
John Dalton: 1805
Dalton’s atomic model is one of the fundamentals of physics as well as chemistry. This theory associated with atomic composition ended up being hypothesized and partially confirmed with the English chemist as well as Physicist John Dalton. Dalton came regarding his Atomic theory as a result of his research into gases. He learned that certain gases only may very well be combined in certain proportions even if two different compounds shared the identical common element or band of elements. Through deductive thinking and experimentation, he made a unique discovery. His findings brought about him to hypothesize that will elements combine for the atomic level in fixed ratios. This ratio might naturally differ in compounds due to unique atomic weights from the elements being put together. This was some sort of revolutionary idea but further experimentation by himself and the like confirmed his theory
