neptunium

= Neptunium = Miles and Devon

Characteristics: Silvery in appearance, Neptunium metal is chemically reactive.
=== History: Enrico Fermi believed that bombarding uranium with neutrons and subsequent beta decay would lead to the formation of element 93. Chemical separation of the new formed elements from the uranium yielded material with low half-life and therefore Fermi announced the discovery of a new element in 1934, although he was soon found to be mistaken. The long search for the mysterious element 93 finally ended in 1952, when it was discovered in Uranium ore. ===
