Atomic Theory Essay, Research Paper Chemistry: A Brief History of Atomic Theory February 28, 1999 In the beginning of the 1800s John Dalton, an English scientist did work some work on gases, which lead him to the creation of a complex system of symbols for all known elements at the time. He took all the information he had collected, along with the Laws of Conservation of Mass, Definite Composition and Multiple Proportions and updated Aristotle’s theory of matter with the Atomic Theory of Matter, which stated: – All matter is composed of tiny, indivisible particles called atoms. – Atoms of an element have identical properties. – Atoms of different elements have different properties. – Atoms of two or more elements can combine in constant ratios to form new substances.
