Contributions of Famous Scientists to Chemistry Essay example

Chemistry is a field of science that has existed for a long time. The history of chemistry dates back to prehistoric times. As chemistry has existed for a long time, scientists classified it into four general chronological categories. These four categories are prehistoric, the beginning of the Christian era, traditional chemistry (alchemy) in the latter half of the 17th century, and modern chemistry. Among the chemists who were first recorded, there are men like Democritus and Aristole. These people lived in the BC era and have great influence on our modern chemistry today. Beginning with Democritus, this person claims that atoms are the simplest unit of matter. Ancient Greek Democrats asked this question.

Among the chemists who were first recorded, there are men like Democritus and Aristole. These people lived in the BC era and have great influence on our modern chemistry today. Beginning with Democritus, this person claims that atoms are the simplest unit of matter. Democrats in ancient Greece asked if we could divide the problem forever and whether the number of times to divide the material is limited.

There is a theory that Democritus eventually becomes small enough to cut. This work is not split. He named this atomic substance Atmo. For Greek democritos, atoms are small, hard particles made of the same material but different in shape and size. He said they can move consistently and unite. Aristotle of ancient Greece raised the theory by arguing that it has only four elements: fire, air, water, and the earth. All substances consist of one of the four elements of these four elements.

Antoine Lavoisier (1743-1794): Antoine Lavoisier is a powerful scientist in chemical history, a chemist in France and is known for its contribution to combustion theory. He also cited oxygen and hydrogen as contradictory to the Phlogiston theory. We also predicted the discovery of two chemical elements, sulfur and silicon. In addition to that, we also proposed a conservation law of mass after reform, a chemical nomenclature, construction of a weighing system, etc. Marie Sklodowska Curie (1867-1934): World famous scientist Marie Curie is the first woman who won the Nobel Prize and is the only scientist who received two Nobel Prizes and two different scientific awards . . Born in Poland, Mary Curie is both a chemist and a physicist. The contribution of her excellent chemist is the discovery of chemical elements, Pol and radium etc.

The famous Swedish chemist Karl Wilhelm Cher was one of the most important natural scientists in 1842 and co-founder of modern chemistry born on 11 December 17, 1742 in Stralsund . Seventh child. As a son of a respected businessman. Since 1775, he is a member of the Swedish Academy of Sciences in Stockholm. Cher discovered various chemical elements and compounds such as manganese, chlorine, tartaric acid, glycerin, lactic acid and so on. Carl Wilhelm Scheele discovered charcoal adsorption gas for the first time. However, his most important achievement is the discovery of oxygen in the air, Carl Wilhelm Scheele is his main work "Chemical Observations and Experiments in the Air and Fire" (Uppsala and Leipzig, M) Stated. Swedish 1777)

Carl Wilhelm Scheele was born in Pomerania (the Baltic coast of northeastern Europe, then was dominated by Swedes). When young, Scheele studied chemistry under the direction of famous chemist Torbern Bergman. Bergman once said that Scheler is one of his greatest discoveries. As laboratory skills in Scheele's chemistry are very strict, his research has promoted some advances in the chemical field. Scheele's achievements in organic chemistry include the separation of glycerol and 12 organic acids such as tartaric acid, citric acid, oxalic acid, mucilage, malic acid, lactic acid, uric acid, gallic acid, tannic acid and the like. In Scheele, the first discovery is bismuth, molybdenum, tungsten. He was the first person to separate elemental phosphorus from bone. Scheele explained graphite (graphite) for the first time as carbon. He is one of the founders of 'activated carbon' adsorbed gas.
