I-About Neptunium
I-Neptunium yi-silvery radioactive actinide ne-transuranium element yokuqala efunyenwe. Iveliswa njengemveliso engapheliyo kwi-nuclear reactors.
Iinkqubo
Ukufumana i-neutroni, i-precursor ye-plutonium-238 (i-space probes), kunye nokukhangela i-nuclear.
Inyathelo 1:
I-Neptunium yayiyeyona nto yokuqala eyenziweyo ye-transuranium element, ivula isango kuzo zonke izinto ezinzima.
