Research Paper On John Dalton

The scientist we chose for our project is John Dalton. Who is John Dalton, you might ask? John Dalton was an English chemist, physicist, and meteorologist. He is best known for the discovery of the modern atomic theory. The rules for the atomic theory are that all matter is made up of tiny particles, or atoms, atoms are always invisible and indestructible, all atoms of a given element are identical in mass and properties, compounds are formed by a combination of two or more different kinds of atoms, and a chemical reaction is a rearrangement of atoms. John Dalton was born on September 6, 1766 in Eaglesfield, England, UK to a Quaker family. He had two surviving siblings, Mary Dalton and Jonathan Dalton, but both he and his brother were born with a case of color blindness. Dalton’s father made a modest income as a handloom weaver, but this still had the family
The first part was that elements are composed of indivisible particles, called atoms. Next was, all atoms of a given element have the same mass, and the mass of an atom of a given element is different from the mass of an atom of any other element. After that was, when elements combine to form compounds, the atoms of one element combine with those of the other element(s) to form molecules. Then was, atoms of two or more elements may combine in different ratios to form different compounds. Finally was his last theory of the atomic theory. The most common ratio of atoms is 1:1, and were more than one compound of two or more elements exists, the most stable is the one with 1:1 ratio of atoms. His fifth theory was proven to be wrong almost immediately after he had shared it in one of his books. The first three theories were slightly modified to become true. The fourth theory has been unable to be proven wrong even with today’s technology. These four atomic theories have been the basic understanding for mass relationship in chemical compounds and chemical
