Nuclear Energy word list, defined
- ATOM /ˈætəm/ · noun
- The smallest unit of an element that retains the chemical properties of that element, consisting of a nucleus of protons and neutrons orbited by electrons. More broadly, the tiniest conceivable particle or amount of something. Related: particle, molecule, unit, speck.
- NUCLEUS /ˈnjuːkliːəs/ · noun
- The central or most important part of something; the core or essence of something. In biology, the nucleus is the control center of a cell. Related: core, center, essence, heart.
- PROTON /ˈproʊtɑːn/ · noun
- A subatomic particle that has a positive charge and is found in the nucleus of an atom. It is one of the three main components of an atom, along with neutrons and electrons. Related: ion, particle, subatomic particle, nucleon.
- NEUTRON /njuːtrɒn/ · noun
- A subatomic particle with no electric charge and a mass slightly greater than that of a proton. Neutrons are found in the nucleus of an atom and play a key role in nuclear reactions. Related: proton, electron, ion, nucleus.
- ELECTRON /ɪˈlɛktrɒn/ · noun
- A stable subatomic particle with a negative electric charge, found in all atoms and moving around the nucleus. Electrons are the primary carriers of electricity in solids and are responsible for chemical bonding. Related: negatron, subatomic particle, charged particle, beta particle.
- FISSION /ˈfɪʃən/ · noun
- The process of splitting into two or more parts, especially the splitting of a heavy atomic nucleus (such as uranium-235) into smaller nuclei with the release of enormous energy. In biology, it also refers to the division of a single-celled organism into two or more daughter cells. Related: splitting, division, cleavage, separation.
- FUSION /ˈfjuːʒən/ · noun
- The process or result of joining two or more distinct things into a single unified whole; in physics, the merging of atomic nuclei with the release of energy. Related: merger, blend, amalgamation, union.
- REACTOR /riːˈæktər/ · noun
- A device or system that produces a chemical or nuclear reaction, especially one that generates power. A person or thing that causes a reaction or response. Related: generator, converter, reactant, catalyst.
- URANIUM /ˈjʊəriəm/ · noun
- A chemical element with the symbol U and atomic number 92, a dense, radioactive, metallic element. Related: radium, actinium, thorium, plutonium.
- PLUTONIUM /ˌpluːtəˈniəm/ · noun
- A radioactive, metallic chemical element with the symbol Pu and atomic number 94. It is a highly toxic, silvery-white metal that is highly reactive and has a number of industrial and military applications. Related: radioactive, toxic, metallic.
- RADIATION /ˌreɪdiˈeɪʃən/ · noun
- The process in which energy is transmitted in the form of electromagnetic waves, or the emission of such waves from a source, such as the sun or a radioactive substance. Radiation can also refer to the emission of high-energy particles, such as alpha, beta, or gamma rays. Related: irradiation, emanation, emission, exposure.
- RADIOACTIVE /ˌreɪdiəʊˈæktɪv/ · adjective
- Giving off or emitting ionizing radiation, especially in the form of alpha, beta, or gamma rays. Emitting ionizing radiation. Related: radioactive, irradiated, contaminated, toxic.
