Did You Know?
It was the first transuranic element (element heavier than uranium) to be synthesized.
It was named after the planet Neptune, following the planetary naming scheme started with uranium (Uranus).
Although it is primarily produced synthetically, trace amounts of neptunium are actually found in nature in uranium ores.
It has been considered for use in devices that can detect high-energy neutrons.
At least 25 radioactive isotopes of neptunium have been identified.
