    Dmitri Mendeleev was one of the most famous modern-day scientists of all time who contributed greatly to the world's fields of science, technology, and politics. He helped modernize the world and set it farther ahead into the future. Mendeleev also made studying chemistry easier, by creating a table with the elements and the atomic weights of them put in order by their properties. Dmitri Ivanovich Mendeleev was born in Tobolsk, Siberia, on February 7, 1834. The blonde-haired, blue-eyed boy was t...

    Chemistry: A Brief History of Atomic Theory February 28, 1999 In the beginning of the 1800 s 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 comp...

    At first glance, nature appears to consist of countless numbers of very different materials. The world thus appears to be an extremely complex mixture of many different materials. But philosophers and scientists have long held another view of the world. They have found it difficult to believe that nature is really as complex as it appears to be. Instead, they have assumed that the many different materials we see result from the combination of a small number of fundamental substances called eleme...
