atomic number 94
Noun: A solid, silvery-grey, radioactive, transuranic element. Its atoms are fissionable (can be split) when bombarded with neutrons. It occurs in minute quantities in uranium ores but is typically produced artificially in nuclear reactors. Thirteen isotopes are known, with plutonium-239 being the most significant.
This term is a scientific name for the chemical element plutonium (symbol Pu). It is used primarily in technical, academic, and nuclear science contexts to specify the element by its fundamental property—the number of protons in its nucleus (94).
Examples: * The reactor's waste contained traces of atomic number 94. * Scientists synthesized atomic number 94 by irradiating uranium-238 with neutrons. * The primary fissile material in the device was an isotope of atomic number 94.
- In nuclear physics and chemistry: The term precisely identifies the element, distinguishing it from others in discussions about the periodic table, nuclear fuel cycles, or radioactive decay chains.
- The research focused on the metallurgical properties of atomic number 94 and its alloys.
- Plutonium (Pu): The common name for the element represented by atomic number 94.
- Transuranic element: A category of elements with atomic numbers greater than 92 (uranium), to which atomic number 94 belongs.
- Fissile material: A descriptor for substances like certain isotopes of atomic number 94 that can sustain a nuclear fission chain reaction.
- Plutonium (This is the direct synonym, the element's name).
This term has a single, precise scientific meaning. It is not used in idiomatic expressions or phrasal verbs. Its usage is confined to contexts where technical specificity is required, such as differentiating it from other elements or emphasizing its defining nuclear property (the proton count).
