Plutonium word list, defined
- 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.
- ACTINIDE /ˈæktɪnaɪd/ · noun
- Any of the series of fifteen metallic chemical elements with atomic numbers 89 through 103, from actinium through lawrencium, all of which are radioactive and occupy the row beneath the lanthanides in the periodic table. Related: actinoid, actinide element.
- TRANSURANIC /trænzʊˈrænɪk/ · adjective
- Exceeding the atomic number 92 (uranium) in the periodic table, referring to elements with atomic numbers greater than 92. Related: radioactive, superheavy, nuclear.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- ATOMIC /əˈtɒmɪk/ · adjective
- Relating to atoms, or to the energy or structure of atoms. More broadly, describing something that is divided into very small, discrete units. Related: nuclear, minute, tiny.
- MASS /mæs/ · noun, verb
- A large amount of something; a quantity of matter. To gather or collect in a large amount. Related: bulk, quantity, amount, heap.
