ETYM New Lat.
One of the transuranic elements.
Silvery, radioactive metallic element of the actinide series, symbol Np, atomic number 93, atomic weight 237.048. It occurs in nature in minute amounts in pitchblende and other uranium ores, where it is produced from the decay of neutron-bombarded uranium in these ores. The longest-lived isotope, Np-237, has a half-life of 2.2 million years. The element can be produced by bombardment of U-238 with neutrons and is chemically highly reactive.
It was first synthesized in 1940 by us physicists E McMillan (1907–) and P Abelson (1913–), who named it for the planet Neptune (since it comes after uranium as the planet Neptune comes after Uranus).
Neptunium was the first transuranic element to be synthesized.
A radioactive transuranic metallic element; found in trace amounts in uranium ores; a by-product of the production of plutonium; SYN. Np, atomic number 93.
