Frederick Soddy FRS [1] (2 September 1877 – 22 September 1956) was an English radiochemist who explained, with Ernest Rutherford, that radioactivity is due to the transmutation of elements, now known to involve nuclear reactions.

Frederick Soddy was an English chemist and recipient of the 1921 Nobel Prize for Chemistry for investigating radioactive substances and for elaborating the theory of isotopes. He is credited, along with others, with the discovery of the element protactinium in 1917.

The Nobel Prize in Chemistry 1921 was awarded to Frederick Soddy "for his contributions to our knowledge of the chemistry of radioactive substances, and his investigations into the origin and nature of isotopes"

Frederick Soddy (1877 – 1956), a chemist whose pioneering discoveries founded the fledgling science of nuclear chemistry, proved that the newly observed phenomenon of radioactivity arose from decay. He also demonstrated that some elements possess isotopes.

Frederick Soddy discovered that all radioactive preparations were not unique elements, but rather that some of them were variants of known elements. In other words, atoms could have the same chemical properties but have different properties when it came to radioactivity.

May 29, 2018 · The English chemist Frederick Soddy (1877-1956) shared in the discoveries of atomic disintegration and of helium production during radioactive decay and introduced the term "isotope" to nuclear science.

Frederick Soddy was a Nobel Prize winning English chemist and physicist. He graduated from Merton College, Oxford with a degree in chemistry. He won the Nobel Prize in Chemistry in 1921.

Frederick Soddy was awarded the Nobel Prize in Chemistry for 1921 “for his contributions to our knowledge of the chemistry of radioactive substances, and his investigations into the origin and nature of isotopes.”
