Ernest Rutherford, 1st Baron Rutherford of Nelson (30 August 1871 – 19 October 1937 [9]), was a New Zealand physicist and chemist who was a pioneering researcher in both atomic and nuclear physics.
Ernest Rutherford, British physicist who discovered that the atom is mostly empty space surrounding a massive nucleus and who did many pioneering experiments with radioactivity.
Ernest Rutherford (1871–1937) postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay. He received the Nobel Prize in Chemistry in 1908.
In 1907, Rutherford took the chair of physics at the University of Manchester. There, he discovered the nuclear nature of atoms and was the world's first successful "alchemist": he converted nitrogen into oxygen. In 1919, he succeeded Sir Joseph Thomson as Cavendish Professor of Physics at Cambridge.
Ernest Rutherford was the first person to split an atom, earning him the title 'Father of Nuclear Physics.' Rutherford's gold foil experiment revealed that atoms have a small, positively charged nucleus with most of the mass. Rutherford hypothesized the neutron's existence and supervised James Chadwick, who discovered the neutron in 1932.
Rutherford eventually coined the terms for some of the most basic principles in the field: alpha, beta, and gamma rays, the proton, the neutron, half-life, and daughter atoms. Several of the...
