Chemistry & Physics: History of the Atom (Dalton, Thomson, Rutherford, and Bohr Models)
Alpha Particles and the Atom
Ernest Rutherford 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 A consummate experimentalist, Rutherford — was responsible for a remarkable series of discoveries in the fields of radioactivity and nuclear physics. He discovered alpha and beta rays, set forth the laws of radioactive decay, and identified alpha particles as helium nuclei. Born on a farm in New Zealand, the fourth of 12 children, Rutherford completed a degree at the University of New Zealand and began teaching unruly schoolboys.
Rutherford's Planetary Model of the Atom. By the components of the atom had been discovered. The atom consisted of subatomic particles called protons and electrons. However, it was not clear how these protons and electrons were arranged within the atom. Thomson suggested the"plum pudding" model.
Rutherford at Manchester, 1907–1919
In , he was the first to discover that atoms have a small charged nucleus surrounded by largely empty space, and are circled by tiny electrons , which became known as the Rutherford model or planetary model of the atom. He is also credited with the discovery of the proton in , and hypothesized the existence of the neutron. Ernest Rutherford was born on 30 August in Spring Grove now called Brightwater near Nelson, New Zealand, the fourth of twelve children of a Scottish farmer and an English schoolteacher. He continued with research work at Canterbury College for a short time, receiving a BSc degree in , before traveling to England in for postgraduate study at the Cavendish Laboratory at the University of Cambridge, where he studied under J. Thompson soon to become the discoverer of the electron. During his nine years in Montreal, Rutherford collaborated with the young Frederick Soddy winner of the Nobel Prize in Chemistry in on ground-breaking research into the transmutation of elements.
