was a British Science Teacher who kept records of the weather. He Suggested that every chemical element consisted of Tiny particles, atoms,Which were identical to each other but different from the atoms of other chemical elements.He also gave names and Symbols to about 30 chemical elements. However, he thought that atoms were solid spheres, like metal balls, which could never be destroyed.Also some Substances that Dalton Believed were element are now Known to be Combinations of elements, or compounds.
Dalton received many honors for the work he did. His Quaker upbringing, and the modesty encouraged in that practice, prompted him to resist public praise. But before his death, he received honorary doctorates from Oxford and Edinburgh University. In 1844, at the age of 77, Dalton died of a stroke. Today, the basic understanding of chemistry is still based on the theories Dalton discovered and explored. Read more at : Study.com
