Areas covered include atomic structure, physical properties, atomic interaction, thermodynamics, identification, atomic size, crystal structure, history, and nomenclature. There were many early false reports of the discovery of neptunium. [138] This compound forms dark green prismatic crystals with maximum edge length 0.15–0.4 mm. Meitnerium Electronic configuration. Neptunium atomic radius is 175 pm, while it's covalent radius is N/A. Neptunium oxides such as Np 3 O 8 and NpO 2 as are also found in the uranium-oxygen system. Possible oxidation states are +3,4,5,6. 93 electrons (white) successively occupy available electron shells (rings). [139] For the former, NpX2+ and NpX+2 (X = Cl, Br) were obtained in 1966 in concentrated LiCl and LiBr solutions, respectively: for the latter, 1970 experiments discovered that the NpO3+2 ion could form sulfate complexes in acidic solutions, such as NpO2SO+4 and NpO2(SO4)−2; these were found to have higher stability constants than the neptunyl ion (NpO2+2).
