Predicting The Existence Of The Neutron
Rutherford carried out calculations of the stability of atomic nuclei. He found that unless some neutral particle were added to the nucleus, the repulsion of the positively charged protons would cause nuclei to fly apart. In 1920 he named this hypothetical particle the neutron.
James Chadwick, Rutherfords Assistant Director of Research, discovered the neutron in 1932, proving its existence by experiment.
He Won The Nobel Prize In Chemistry In 1908
Ernest Rutherford was a New Zealand-born British physicist, who postulated the nuclear structure of the atom, which led to the exploration of nuclear physics. He discovered alpha and beta rays, and proposed the laws of radioactive decay. He is often called the “father of nuclear physics”.
Ernest Rutherford was born in 1871, in Nelson, New Zealand. Ernest received a double major in Mathematics and Physical Science from Canterbury College, the University of New Zealand, Wellington in 1893. He was awarded an Exhibition Science Scholarship, enabling him to go to Trinity College, Cambridge, the U.K., as a research student at the Cavendish Laboratory under J.J. Thomson, who was an expert on electromagnetic radiation. In 1895, Rutherford developed a simple apparatus to detect electromagnetic waves, or radio waves.

What Is Radioactive Decay In Nuclear Physics
The starting point of nuclear physics is the phenomenon called radioactive decay. This is the process in which an atom releases radiation in the form of particles or electromagnetic waves . During decay, atoms transform into lighter elements. As time progresses, the decay process converts every radioactive substance into another one. The moment when the substances have decayed to half their original quantity is called half time.
Radioactive decay is a spontaneous and stochastic process. The process follows a specific rate. Even if we dont know which atom will decay, we can approximate how much substance will be left after some time, and the average time it will take for it all to decay.

Father Of Nuclear Chemistry Otto Emil Hahn
Known as father of nuclear chemistry, Otto Emil Hahn was a German chemist who was one of the early pioneers of radioactivity and radiochemistry. Hahn won the Nobel Prize in Chemistry for his historic discovery of nuclear fission. He was nominated for the Nobel Prize in Chemistry 22 times and 16 times for the Nobel Prize in Physics before he finally became a Nobel Laureate in 1944.
Otto Hahn, along with his long-time collaborator in research Prof. Lise Meitner, and his student Fritz Strassmann began to research the bombardment of uranium nuclei, leading to the discovery of what came to be known as nuclear fission.
Among all radioactive elements discovered by Otto Hahn, mesothorium-1 was a significant one. Mesothorium-1 is a radioactive element that cost half as much to manufacture as Radium-226 that had been discovered by Pierre and Marie Curie, but was equally effective for use in radiation therapy for cancer patients. This discovery won his first nomination for the 1914 Nobel Prize in Chemistry. However that year, he didnt win it, but mesothorium began to be used widely for all cancers.
In 1905, on Ramsays recommendation, Rutherford asked Hahn to join him at McGill University in Montreal, Canada. Here, Hahn discovered other new radioactive isotopes before returning to Germany and joining Emil Fischers institute at the University of Berlin in 1906, rising quickly through the faculty ranks to become a Professor of Chemistry.

Celebrating Ernest Rutherford’s 150th Birthday
Throughout August 2021, we are celebrating the 150th birthday of Ernest, Lord Rutherford father of nuclear physics and the University of Canterbury’s most distinguished graduate.
Ernest Rutherford was the creator of modern atomic and nuclear physics – one of the greatest scientists of the twentieth century. He started at the University of Canterbury in 1890. After three degrees and two years research at the forefront of the electrical technology of the day, he won an 1851 Exhibition Scholarship, which he took up at the Cavendish Laboratory, Cambridge.
He made discoveries about radioactivity, transmutation of elements in nuclear interactions, and most notably the discovery that all atoms consist of a dense, charged nucleus surrounded by tiny electrons in mostly empty space. Rutherford was awarded the 1908 Nobel Prize in chemistry and later made a baron for his contributions to science.

Rutherford Model Of The Atom
The Rutherford model was a model of the atom devised by Ernest Rutherford. He performed his famous Geiger-Marsden experiment , which showed that the Plum pudding model of the atom was incorrect. Rutherford’s new model for the atom had a number of essential modern features, including a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom.
In the Geiger-Marsden experiment which Rutherford directed, alpha particles were used as a probe into atomic structure by being allowed to pass through a thin piece of gold foil, then detected. Rutherford predicted that all of the particles would pass through the foil, or be deflected slightly. This is what happened most of the time, but a small proportion of particles bounced unexpectedly nearly straight back toward the source. This supported the hypothesis that atoms have a dense region containing most of their mass, and associated with a highly concentrated electric field , instead of spread-out positive or negative field. Rutherford thought it likely, on purely symmetric and aesthetic grounds, that such a region of dense charge and mass would be located in the atom’s center. Such a region “would then form a sort of atomic core.”
For concreteness, consider the passage of a high speed a particle through an atom having a positive central charge N e, and surrounded by a compensating charge of N electrons.
Later Years And Honours
Rutherford was knighted in 1914. During World War I, he worked on a top secret project to solve the practical problems of submarine detection by sonar. In 1916, he was awarded the Hector Memorial Medal. In 1919, he returned to the Cavendish succeeding J. J. Thomson as the Cavendish professor and Director. Under him, Nobel Prizes were awarded to James Chadwick for discovering the neutron , John Cockcroft and Ernest Walton for an experiment which was to be known as splitting the atom using a particle accelerator, and Edward Appleton for demonstrating the existence of the ionosphere. In 1925, Rutherford pushed calls to the New Zealand Government to support education and research, which led to the formation of the Department of Scientific and Industrial Research in the following year. Between 1925 and 1930, he served as President of the Royal Society, and later as president of the Academic Assistance Council which helped almost 1,000 university refugees from Germany. He was appointed to the Order of Merit in the 1925 New Year Honours and raised to the peerage as Baron Rutherford of Nelson, New Zealand and of Cambridge in the County of Cambridge in 1931, a title that became extinct upon his unexpected death in 1937. In 1933, Rutherford was one of the two inaugural recipients of the T. K. Sidey Medal, set up by the Royal Society of New Zealand as an award for outstanding scientific research.

The Age Of Planet Earth And Radiometric Dating
Rutherford realized that Earths helium supply is largely produced by the decay of radioactive elements. He devised a method of dating rocks relating their age to the amount of helium present in them.
Based on the fact that our planet is still volcanically active, Lord Kelvin had indicated Earths age could be no greater than 400 million years old. He said Earth could be older than this only if some new source of energy could be found that was heating it internally.
Rutherford identified the new source the energy released by radioactive decay of elements.
He also began the science of radiometric dating using the products of radioactive decay to find out how old things are.
Tube Alloys And The Maud Report
In Germany, Otto Hahn and Fritz Strassmann bombarded uranium with neutrons, and noted that barium, a lighter element, was among the products produced. Hitherto, only the same or heavier elements had been produced by the process. In January 1939, Meitner and her nephew Otto Frisch astounded the physics community with a paper that explained this result. They theorised that uranium atoms bombarded with neutrons can break into two roughly equal fragments, a process they called fission. They calculated that this would result in the release of about 200 MeV, implying an energy release orders of magnitude greater than chemical reactions, and Frisch confirmed their theory experimentally. It was soon noted by Hahn that if neutrons were released during fission, then a chain reaction was possible. French scientists, Pierre Joliot, Hans von Halban and Lew Kowarski, soon verified that more than one neutron was indeed emitted per fission. In a paper co-authored with the American physicist John Wheeler, Bohr theorised that fission was more likely to occur in the uranium-235isotope, which made up only 0.7 percent of natural uranium.

The Balance Of Forces In The Nucleus
An atom has protons and neutrons in its nucleus. Protons are positively charged particles, while neutrons have no charge. Protons repel each other due to their electrostatic force. However, there is another force, called the strong nuclear force, which counterbalances the electrostatic force and works to keep the neutrons and protons glued together.
The strong nuclear force attracts the protons and neutrons but keeps them at a fixed distance. It attracts particles at a certain distance but repels them when they come too close.
Figure 4. The balance of the electrostatic force and the strong nuclear force keeps the nucleus glued together. Radioactive decay occurs when that balance breaks down. Source: Manuel R. Camacho, StudySmarter.

Mcgill University In Canada
Rutherfords strong research skills won him a professorship at McGill University in Montreal, Canada. In the fall of 1898 Rutherford started his position as a professor of physics at McGill. During the summer of 1900 after two years of concentrated work on the radioactive nature of thorium, he traveled back to New Zealand to marry his impatient bride. The newlyweds returned to Montreal that fall and began their life together.
Rutherford worked closely with his able assistant Frederick Soddy starting in 1902 and the pair followed up on a discovery by William Crookes who had found that uranium formed a different substance as it gave off radiation. Through careful laboratory research, Rutherford and Soddy demonstrated that uranium and thorium broke down in the course of radioactivity into a series of intermediate elements. Rutherford observed that during each stage of the transmutation process different intermediate elements broke down at a particular rate so that half of any quantity was gone in a fixed amount of time, which Rutherford called the half-lifea term still in use today.
