Document Summary
Chem 101: the history of the foundations of chemistry and the concepts of. Early modern greeks into the development of modern chemistry. The early greeks, mainly that of democritus and his master theocritus, conceptualized that everything in the universe was made up of very small unbreakable particles and empty space. In 1808, modern chemist john dalton created the fundamental understanding of modern chemistry known as the atomic theory. The atomic theory states 4 very simple things: 1. Each element is made up of small indestructible particles called atoms. The mass of an atom distinguishes the difference between elements. Atoms combine in simple whole ratio numbers in order to create new molecules. Atoms of one element cannot change into an atom of another element. From there, other laws were established by other chemists. Proust established the law of definite proportions that states that the properties of a given compound are similar to the properties of its constituent elements.
