    1). He wrote the first extensive list of elements containing 33 elements and distinguished metals and non-metals (source 5). Him and his area of work were particularly interested in compounds, element weight and chemical reaction (source 6). Dimitri Mendeleev arranged 63 known elements, into the periodic table based on atomic mass and predicted the existence and properties of new elements. He realised that the physical and chemical properties of elements were related to their atomic mass and arranged

    10,000 BC. The ancient civilizations used technologies that came to become the makeup of the many branches of chemistry. These early civilizations would extract metal from ores, make pottery and glazes, beer and wine fermentation, extraction of chemicals from plants for medicine, making fat into soap, making glass, and many chemistry related tasks were done. Alchemists set the stage for modern chemistry by performing experiments and recording the results. Robert Boyle wrote The Sceptical Chymist
