WebNiels Bohr was born in Copenhagen on October 7, 1885. In 1911 did experimental work going on in the Cavendish Laboratory under J.J. Thomson's guidance and In 1912 he was at work in Rutherford’s laboratory in Manchester. [1] In 1913 Bohr analysed the spectral lines of hydrogen. This meant that he observed the coloured lines (wavelengths given ... WebDalton's ideas proved foundational to modern atomic theory. However, one of his underlying assumptions was later shown to be incorrect. Dalton thought that atoms were the smallest units of matter −-− minus tiny, hard spheres that could not be broken down any further. This assumption persisted until experiments in physics showed that the atom …
