Atomic Number 93 (Noun)
Meaning
A radioactive transuranic metallic element; found in trace amounts in uranium ores; a by-product of the production of plutonium.
Classification
Nouns denoting substances.
Examples
- The atomic number 93, also known as neptunium, is a radioactive transuranic metallic element commonly found in trace amounts in uranium ores.
- Neptunium, with the atomic number 93, was first discovered in 1940 by Edwin McMillan and Philip Abelson.
- The production of plutonium often results in the creation of neptunium as a by-product, due to the atomic number 93 being a midpoint in the synthetic process.
- Due to the element's low natural abundance and the difficulty in obtaining it from uranium ores, neptunium with the atomic number 93 is typically synthesized artificially.
- As an element with the atomic number 93, neptunium remains one of the lesser-studied and more unusual elements in the periodic table.
