Isotopes of neptunium 錼的同位素
(重定向自Neptunium 237)
Neptunium (Np) is an artificial element, and thus a standard atomic mass cannot be given. Like all artificial elements, it has no stable isotopes. The first isotope to be synthesized was Np in 1940, produced by bombarding U with neutrons to produce U, which then underwent beta decay to Np.
