What are 2 interesting facts about neptunium?

Neptunium, element 93 on the periodic table of elements, was the first transuranium element to be produced synthetically and the first actinide series transuranium element to be discovered. Its discovery came after several false findings of the element, including Enrico Fermi’s attempt to bombard uranium with neutrons.
