Soddy

Fredrick Soddy (2 September 1877 – 22 September 1956) was an English who explained that "radioactivity" was occurring because of the transmutation of elements. He went to school at Eastbourne college, before going on to study at Universiry college of Whales at Aberystwyth and at Merton college, Oxford. He was a researcher at Oxford from 1898 to 1900. In 1903 he observed, in an experiment, that decaying Radium lasted in alpha particles composed of positively charged nuclei of helium. He wondered why this was happening to decaying particles, he conducted many experiments. After a while he found out that an atom moves lower in atomic number by two places on alpha emission, higher by one place on beta emission. This was a new revelation to the science community and in May 1910, Soddy was elected a Fellow of the Royal Society. In 1914 he was appointed to chair at the University of Aberdeen. After then he got married to Winfred Beilby, the daughter of Sir George Beilby in 1908. He died in Brighton, England  in 1956.
