Accomplishments of John Dalton
John Dalton once made this famous quote on his work concerning the atom, " We might as well attempt to introduce a new planet into the solar system, or to annihilate one already in existence, as to create or destroy a particle of hydrogen."John Dalton was a British chemist and physicist, who developed the atomic theory upon which modern physical science is founded. Dalton, a Quaker, was born on September 6, 1766, in Eaglesfield, Cumberland County, England. He received education from the village school until age 11. He received tuition from Elihu Robinson, a wealthy Quaker, meteorologist, and instrument maker, who first encouraged Dalton's interest in meteorology. At age 12 he was given a job to teach at the same school he attended. He worked on a farm for two years before he moved to Kendal where he taught with his brother. He also went on to teach at a Presbyterian Institute when he was 28 years old. A year later he was elected to the Manchester Literacy and Philosophical Society. Althoug
In 1803 Dalton made his most important contribution to science, his theory (The atomic theory) states that matter is composed of atoms of differing weights and combine in simple ratios by weight. A physical clue to the theory was provided by the solubility of gases in water. He found through experiments that atoms of different gases have different weights. He showed how these atoms link together in definite proportions. An atom is any of the smallest particles of an element that combine with similar particles of other elements to produce compounds. He first announced his theory at a Royal Institution in a lecture in 1803. This theory was the foundation of modern physical science. Dalton used his theory to rationalize the various laws of chemical combination and show that they followed his theory. The postulates of the theory are that matter consists of atoms; that atoms can be neither created or destroyed; that all atoms of the same element are identical; different elements have different types
