This was a problem for nuclear physics at the time, because it seemed to indicate that energy was not conserved in these decays.

The Nobel Prize in Physics was awarded jointly to Becquerel for his discovery and to Marie and Pierre Curie for their subsequent research into radioactivity. Rutherford was awarded the Nobel Prize in Chemistry in for his "investigations into the disintegration of the elements and the chemistry of radioactive substances". In Albert Einstein formulated the idea of mass—energy equivalence. While the work on radioactivity by Becquerel and Marie Curie predates this, an explanation of the source of the energy of radioactivity would have to wait for the discovery that the nucleus itself was composed of smaller constituents, the nucleons.

More work was published in by Geiger and Ernest Marsden , [7] and further greatly expanded work was published in by Geiger.

The key experiment behind this announcement was performed in at the University of Manchester : Ernest Rutherford's team performed a remarkable experiment in which Geiger and Marsden under Rutherford's supervision fired alpha particles helium nuclei at a thin film of gold foil.

The plum pudding model had predicted that the alpha particles should come out of the foil with their trajectories being at most slightly bent.

But Rutherford instructed his team to look for something that shocked him to observe: a few particles were scattered through large angles, even completely backwards in some cases.

He likened it to firing a bullet at tissue paper and having it bounce off. The discovery, with Rutherford's analysis of the data in , led to the Rutherford model of the atom, in which the atom had a very small, very dense nucleus containing most of its mass, and consisting of heavy positively charged particles with embedded electrons in order to balance out the charge since the neutron was unknown.

As an example, in this model which is not the modern one nitrogen consisted of a nucleus with 14 protons and 7 electrons 21 total particles and the nucleus was surrounded by 7 more orbiting electrons.

Around , Arthur Eddington anticipated the discovery and mechanism of nuclear fusion processes in stars , in his paper The Internal Constitution of the Stars. This was a particularly remarkable development since at that time fusion and thermonuclear energy, and even that stars are largely composed of hydrogen see metallicity , had not yet been discovered. The Rutherford model worked quite well until studies of nuclear spin were carried out by Franco Rasetti at the California Institute of Technology in Rasetti discovered, however, that nitrogen had a spin of 1.

With the discovery of the neutron, scientists could at last calculate what fraction of binding energy each nucleus had, by comparing the nuclear mass with that of the protons and neutrons which composed it. Differences between nuclear masses were calculated in this way. Proca's equations of the massive vector boson field[ edit ] Alexandru Proca was the first to develop and report the massive vector boson field equations and a theory of the mesonic field of nuclear forces.

In the Yukawa interaction a virtual particle , later called a meson , mediated a force between all nucleons, including protons and neutrons. This force explained why nuclei did not disintegrate under the influence of proton repulsion, and it also gave an explanation of why the attractive strong force had a more limited range than the electromagnetic repulsion between protons.

Later, the discovery of the pi meson showed it to have the properties of Yukawa's particle. With Yukawa's papers, the modern model of the atom was complete.

The center of the atom contains a tight ball of neutrons and protons, which is held together by the strong nuclear force, unless it is too large. Unstable nuclei may undergo alpha decay, in which they emit an energetic helium nucleus, or beta decay, in which they eject an electron or positron.

After one of these decays the resultant nucleus may be left in an excited state, and in this case it decays to its ground state by emitting high energy photons gamma decay. The study of the strong and weak nuclear forces the latter explained by Enrico Fermi via Fermi's interaction in led physicists to collide nuclei and electrons at ever higher energies.

This research became the science of particle physics , the crown jewel of which is the standard model of particle physics which describes the strong, weak, and electromagnetic forces. Modern nuclear physics[ edit ] Main articles: Liquid-drop model , Nuclear shell model , and Nuclear structure A heavy nucleus can contain hundreds of nucleons.

This means that with some approximation it can be treated as a classical system , rather than a quantum-mechanical one. In the resulting liquid-drop model , [19] the nucleus has an energy which arises partly from surface tension and partly from electrical repulsion of the protons. The liquid-drop model is able to reproduce many features of nuclei, including the general trend of binding energy with respect to mass number, as well as the phenomenon of nuclear fission.

Superimposed on this classical picture, however, are quantum-mechanical effects, which can be described using the nuclear shell model , developed in large part by Maria Goeppert Mayer [20] and J.

Hans D. Other more complicated models for the nucleus have also been proposed, such as the interacting boson model , in which pairs of neutrons and protons interact as bosons , analogously to Cooper pairs of electrons.

Ab initio methods try to solve the nuclear many-body problem from the ground up, starting from the nucleons and their interactions. Nuclei may also have extreme shapes similar to that of Rugby balls or even pears or extreme neutron-to-proton ratios. Experimenters can create such nuclei using artificially induced fusion or nucleon transfer reactions, employing ion beams from an accelerator.

Beams with even higher energies can be used to create nuclei at very high temperatures, and there are signs that these experiments have produced a phase transition from normal nuclear matter to a new state, the quark—gluon plasma , in which the quarks mingle with one another, rather than being segregated in triplets as they are in neutrons and protons.

Main articles: Radioactivity and Valley of stability Eighty elements have at least one stable isotope which is never observed to decay, amounting to a total of about stable isotopes. However, thousands of isotopes have been characterized as unstable. These "radioisotopes" decay over time scales ranging from fractions of a second to trillions of years.

Plotted on a chart as a function of atomic and neutron numbers, the binding energy of the nuclides forms what is known as the valley of stability.

Stable nuclides lie along the bottom of this energy valley, while increasingly unstable nuclides lie up the valley walls, that is, have weaker binding energy.

The most stable nuclei fall within certain ranges or balances of composition of neutrons and protons: too few or too many neutrons in relation to the number of protons will cause it to decay. For example, in beta decay a nitrogen atom 7 protons, 9 neutrons is converted to an oxygen atom 8 protons, 8 neutrons [23] within a few seconds of being created. In this decay a neutron in the nitrogen nucleus is converted by the weak interaction into a proton, an electron and an antineutrino.
