Biography on John Dalton

rear end Dalton an English chemist and physicist, was cognize to us for his atomic theory. innate(p) in 1766, September, and taught by his father. He started t separatelying people at the upstart age of 12, precisely since he was discontent with the wage he got, which was vindicatory about 5 shillings, he started kitchen-gardening for two years. Later, at 1793, he studied mathematics and indwelling philosophy at the Manchester Academy. At 1800, he publish his atomic theory, explaining how and why elements would compound with one a nonher in repair ratios and more or lesstimes also in multiples of those ratios. Inside his theory, he give tongue to the following main points: 1. Elements argon make out of tiny particles called atoms 2. The atoms of each element atomic number 18 the analogous, having the same mass 3. Compounds have a burnish up ratio of atoms, so they have a regular compositions 4. Atoms of each element are different, having different mass 5. Chemical reactions are just rearranging the combinations of the atoms, and atoms can not be destroyed The theory that John Dalton stated have persuaded half(a) of the scientists of that time, with oppositions dying off half a century later, since he added this to his theory: When atoms combine in entirely one ratio, ...it must be presumed to be a binary star one, unless roughly cause appear to the contrasted.

It was proved proper later, but caused his theory to be unestablished by some scientists. Other contributions he gave us was his contribution on colour blindness. Since he was coloured-blinded himself, nonracist was sometimes called Daltonism. John Dalton died at Manchester of paralysis. He firstly suffered from it since 1837, when he got his first stroke. After finishing his perish experiment, he was entrap on the spur of the moment felling off his bed, by his assistant. A sculpture of his head...
