Biography on John Dalton

tush Dalton an English chemist and physicist, was know to us for his atomic theory. innate(p) in 1766, September, and taught by his father. He started t separatelying people at the five-year-old age of 12, solely 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 math and indwelling philosophy at the Manchester Academy. At 1800, he publish his atomic theory, explaining how and why elements would integrate 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 quest main points: 1. Elements argon do out of tiny particles called atoms 2. The atoms of for each one element be the alike(p), having the same mass 3. Compounds have a smooth up ratio of atoms, so they have a continual 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 one- 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 moldiness be presumed to be a binary star one, unless around cause appear to the stubborn.

It was proved proper later, but caused his theory to be unrecognised 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 root suffered from it since 1837, when he got his first stroke.
