Uranium word list, defined
- URANIUM /ˈjʊəriəm/ · noun
- A chemical element with the symbol U and atomic number 92, a dense, radioactive, metallic element. Related: radium, actinium, thorium, plutonium.
- 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.
- 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.
- ISOTOPE /ˈaɪsoʊtəp/ · noun
- An atom of an element that has a particular number of neutrons in its nucleus, leading to a different atomic mass from other atoms of the same element. Related: nuclide, radionuclide, isobar, isomer.
- 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.
- 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.
- DECAY /dɪˈkeɪ/ · verb and noun
- To decay is to rot or decompose through natural processes, or to decline gradually in quality, condition, or strength. As a noun, decay refers to the state or process of rotting, decomposition, or gradual deterioration. Related: rot, decompose, deteriorate, wither.
- ALPHA /ˈælfə/ · noun
- The first letter of the Greek alphabet (Α, α). More broadly, the first or most dominant item in a series, or an animal ranked highest in a social hierarchy. Related: beginning, first, leading, dominant.
