A chemist is a Scientist trained in the Science of Chemistry . In the British Isles and some Commonwealth countries, ''chemist'' may also refer to a Dispensing Chemist , a Pharmacist , or a general retailer of chemicals (usually for medicinal purposes). Chemists study the composition of matter and its small-scale properties such as Density and Acidity instead of large-scale properties like size and shape. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of Molecules and their component Atom s. Chemists carefully measure substance proportions, Reaction rates, and other Chemical Properties . Chemists use this knowledge to learn the composition, structure, and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of Subdisciplines Of Chemistry . Materials Scientists share much of the same education and skills with chemists. EDUCATION Jobs for chemists usually require at least a Bachelor's Degree , but many positions, especially those in research, require a PhD . Most undergraduate programs emphasize Mathematics and Physics as well as chemistry. At the Master's level and higher, students tend to specialize in a particular field. Fields of specialization include Biochemistry , Organic Chemistry , Inorganic Chemistry , Analytical Chemistry , and Physical Chemistry . Post-doctorate experience may be required for certain positions. EMPLOYMENT The three major employers of chemists are academic institutions, industry, especially the Chemical Industry and the Pharmaceutical Industry , and government laboratories. Chemistry typically is divided into several major sub-disciplines. There are also several main cross-disciplinary and more specialized fields of chemistry. There is a great deal of overlap between different branches of chemistry, as well as with other scientific fields such as biology, medicine, physics, and several engineering disciplines.

HISTORY Main article: History Of Chemistry The word ''chemist'' is a Corruption of the New Latin Noun ''chimista'', an Abbreviation of ''alchimista'' ( Alchemist ). The roots of chemistry can be traced to the phenomenon of Burning . Fire was a mystical force that transformed one substance into another and thus was of primary interest to mankind. It was fire that led to the discovery of Iron and Glass . After Gold was discovered and became a precious metal, many people were interested to find a method that could convert other substances into gold. This led to the Protoscience called Alchemy . Alchemists discovered many chemical Processes that led to the development of modern chemistry. Chemistry as we know it today, was invented by Antoine Lavoisier with his law of Conservation Of Mass in 1783. The Discoveries Of The Chemical Elements has a long history culminating in the creation of the Periodic Table by Dmitri Mendeleyev . The Nobel Prize In Chemistry created in 1901 gives an excellent overview of chemical discovery in the past 100 years. SEE ALSO
