Origin of 'neptunium'
Main points about word origin
- The name comes from the planet Neptune, following the naming convention of uranium, which is derived from the planet Uranus.
- First discovered in 1940, it was the first transuranium element created by humans.
The name 'neptunium' was first coined in 1940 by Edwin McMillan and Philip H. Abelson, who discovered the element at the University of California, Berkeley. The name is derived from 'Neptune', the planet that follows Uranus in the solar system, reflecting its position in the periodic table as the element following uranium. The discovery of neptunium marked a significant achievement in nuclear chemistry, as it was the first element to be synthesized that was heavier than uranium, thus expanding the known elements beyond the naturally occurring ones. The element was first isolated in a pure form in 1945, and its properties significantly contributed to understanding the actinide series and nuclear reactions.
