How did chadwick contribute to isotopes
WebJ. J. Thomson took science to new heights with his 1897 discovery of the electron – the first subatomic particle. He also found the first evidence that stable elements can exist as isotopes and invented one of the most powerful tools in analytical chemistry – the mass spectrometer. Advertisements Beginnings: School and University WebHe established that an atom includes a tiny, positively charge nucleus, which is surrounded by electrons. Both John Dalton and Ernest Rutherford, among other great researchers and scientists, assisted in creating the atomic theory that exists today. Dalton's theory was the first modern atomic theory, but a part of it was disproven by Rutherford.
