Nuclear Energy is energy due to the splitting (fission) of the nuclei of atom(s). In Physics and other Sciences energy (from the Greek grc ἐνέργεια - Energeia, "activity operation" from grc ἐνεργός History See also Atomic theory, Atomism The concept that matter is composed of discrete units and cannot be divided into arbitrarily tiny The conversion of nuclear mass to energy is consistent with the mass-energy equivalence formula ΔE = Δm. Mass is a fundamental concept in Physics, roughly corresponding to the Intuitive idea of how much Matter there is in an object In Physics, mass–energy equivalence is the concept that for particles slower than light any Mass has an associated Energy and vice versa. c², in which ΔE = energy release, Δm = mass defect, and c = the speed of light in a vacuum (a physical constant). Binding energy is the Mechanical energy required to disassemble a whole into separate parts This vacuum means "absence of matter" or "an empty area or space" for the cleaning appliance see Vacuum cleaner. A physical Constant is a Physical quantity that is generally believed to be both universal in nature and constant in time

Nuclear energy is released by three exoenergetic (or exothermic) processes:

• Radioactive decay, where a neutron or proton in the radioactive nucleus decays spontaneously by emitting either particles, electromagnetic radiation (gamma rays), neutrinos (or all of them)
• Fusion, two atomic nuclei fuse together to form a heavier nucleus
• Fission, the breaking of a heavy nucleus into two (or more rarely three) lighter nuclei

Nuclear energy was first discovered by French physicist Henri Becquerel in 1896, when he found that photographic plates stored in the dark near uranium were blackened like X-ray plates, which had been just recently discovered at the time 1895. In Thermodynamics, the word exothermic "outside heating" describes a process or reaction that releases Energy usually in the form of Heat, but Radioactive decay is the process in which an unstable Atomic nucleus loses energy by emitting ionizing particles and Radiation. Radioactive decay is the process in which an unstable Atomic nucleus loses energy by emitting ionizing particles and Radiation. In Physics and Nuclear chemistry, nuclear fusion is the process by which multiple- like charged atomic nuclei join together to form a heavier nucleus Nuclear fission is the splitting of the nucleus of an atom into parts (lighter nuclei) often producing Free neutrons and other smaller nuclei which may This article is about the country For a topic outline on this subject see List of basic France topics.

Nuclear chemistry can be used as a form of alchemy to turn lead into gold or change any atom to any other atom (albeit through many steps). Nuclear chemistry is a subfield of Chemistry dealing with Radioactivity, nuclear processes and nuclear properties Alchemy a part of the Occult Tradition is both a philosophy and a practice with an ultimately unknown aim involving the improvement of the alchemist as well as the making of Characteristics Lead has a dull luster and is a dense, Ductile, very soft highly Gold (ˈɡoʊld is a Chemical element with the symbol Au (from its Latin name aurum) and Atomic number 79 ^[2] Radionuclide (radioisotope) production often involves irradiation of another isotope (or more precisely a nuclide), with alpha particles, beta particles, or gamma rays. A radionuclide is an Atom with an unstable nucleus, which is a nucleus characterized by excess energy which is available to be imparted either to a newly-created Isotopes (Greek isos = "equal" tópos = "site place" are any of the different types of atoms ( Nuclides A nuclide (from lat nucleus is a species of Atom characterized by the constitution of its nucleus and hence by the number of Protons, the number of Alpha particles (named after and denoted by the first letter in the Greek alphabet, α consist of two Protons and two Neutrons bound together into a Beta particles are high-energy high-speed Electrons or Positrons emitted by certain types of Radioactive nuclei such as Potassium -40 Gamma rays (denoted as &gamma) are a form of Electromagnetic radiation or light emission of frequencies produced by sub-atomic particle interactions

Iron has the highest binding energy per nucleon of any atom. Iron (ˈаɪɚn is a Chemical element with the symbol Fe (ferrum and Atomic number 26 In Physics a nucleon is a collective name for two Baryons the Neutron and the Proton. If an atom of lower average binding energy is changed into an atom of higher average binding energy, energy is given off. The chart shows that fusion of hydrogen, the combination to form heavier atoms, releases energy, as does fission of uranium, the breaking up of a larger nucleus into smaller parts. Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 Stability varies between isotopes: the isotope U-235 is much less stable than the more common U-238. Uranium-235 is an isotope of uranium that differs from the element's other common isotope Uranium-238, by its ability to cause a rapidly expanding fission Uranium-238 (U-238 is the most common isotope of Uranium found in nature
