John Dalton Biography

John Dalton Biography: 6 September 1766 Death: July 27, 1844 Age: 78 Description: British chemist and physicist, he developed atomistic theory of matter and hence the name of modern physics . One of the pioneers. Dalton is the son of Quaker Weaver. At only 12 years old, he was in charge of Cumberland's Quaker School and two years later he taught with his older brother at Kendall's school where he will stay for 12 years. After that, he became a teacher of mathematics and natural philosophy at the new University of Manchester.

& Lt; Tab / & gt; John Dalton is a British chemist and has discovered the first useful material atomism theory. John Dalton discovered this theory in 1803 (Cain, 2001). According to John Dalton's atomic theory, all substances are composed of invariant and invariant atoms, characterized by the mass of the element, and the compound is formed by a combination of two or more different atoms. Destruct, destroy, or convert other kinds of atoms during chemical reaction. Many of the ideas of Dalton were obtained from other chemists at that time, such as Laboasier and Higgins. However, Dalton was the first person to incorporate these ideas into the universal atomism theory and was definitely his greatest achievement (Wikipedia, 2004).

At the beginning of the 19th century, John Dalton discovered that atom. It gives the way to the idea that a chemical reaction is actually a transition of an atomic group called a molecule. Dalton also said that the emergence and extinction of nature means that atomic composition means determining the appearance of different properties. He also proposed the idea that the molecule of matter is identical to other molecules of the same substance. From studies of these and many other chemists, we now have a fairly comprehensive understanding of chemical reactions. There are many classification systems for classifying various kinds of reactions. These include decomposition, polymerization, chain reaction, substitution reaction, elimination reaction, addition reaction, ion reaction and redox reaction.

John Dalton was born in Eaglesfield, Cumberland, England on September 5, 766. Dalton lives in a small mansion with his family. His family has been Quaker since 1690. Quaker members are friends of society. John had brothers named Mary and a brother named Charles, when he was born, his brother was only 12 years old and his sister was only 2 years old. Since the birth of Dalton was not recorded, when he grew, he asked one of his relatives and got it to be his birthday and answered. His parents are sincere people and excellent workers. His father Joseph had inheritance of his land, and Dalton and his brother Charles helped to harvest the crop. His mother Deborah Greenup, sister of plain textile Dalton also helped her. John Dalton's family is poor, but "they are not hungry nevertheless they are poor"
