A radioactive actinide metal, neptunium is the first transuranic element. en.wikipedia.org

Ions of neptunium are prone to hydrolysis and formation of coordination compounds. en.wikipedia.org

This amount declines slowly as the americium decays into neptunium-237, a different transuranic element with a much longer half-life (about 2.14 million years). en.wikipedia.org

Neptunium dioxide has also been show to contribute to increased decay rates of radioactive metals, an application which is currently being explored. en.wikipedia.org

With its half-life of 432.2 years, the americium in a smoke detector includes about 3% neptunium after 19 years, and about 5% after 32 years. en.wikipedia.org

O to various temperature thresholds and further heating will also cause these compounds to exhibit different neptunium allotropes. en.wikipedia.org

By weight, neptunium-237 discharges are about 5% as great as plutonium discharges and about 0.05% of spent nuclear fuel discharges. en.wikipedia.org

Examples include gallium, ytterbium, bismuth, mercury and neptunium. en.wikipedia.org

The element 93 was synthesised in 1940 and named neptunium. en.wikipedia.org

The relative order of the middle two neptunium ions depends on the ligands and solvents used. en.wikipedia.org
