neptunium
[ nษpหtjuหniษm ]
chemical element
Neptunium is a radioactive metallic element with the symbol Np and atomic number 93. It is part of the actinide series and is the first transuranic element, which means it is heavier than uranium. Neptunium is used in some types of nuclear reactors and for research purposes.
Examples of usage
- Neptunium isotopes are utilized in scientific analysis.
- Researchers studied the properties of neptunium in their experiments.
- Neptunium-237 is a significant isotope with applications in nuclear science.

Etymology
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.
