In early work, Rutherford discovered the concept of radioactive half-life , the radioactive element radon, [4] and differentiated and named alpha and beta radiation. It is the basis for the Nobel Prize in Chemistry he was awarded in "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances", [6] for which he was the first Canadian and Oceanian Nobel laureate. Rutherford moved in to the Victoria University of Manchester today University of Manchester in the UK, where he and Thomas Royds proved that alpha radiation is helium nuclei. He performed the first artificially induced nuclear reaction in in experiments where nitrogen nuclei were bombarded with alpha particles. As a result, he discovered the emission of a subatomic particle which, in , he called the "hydrogen atom" but, in , he more accurately named the proton. Under his leadership the neutron was discovered by James Chadwick in and in the same year the first experiment to split the nucleus in a fully controlled manner was performed by students working under his direction, John Cockcroft and Ernest Walton.
