Neptunium chemistry is covered in this lecture. Nuclear properties and synthesis of neptunium are described, with emphasis placed on the isotopes 235-239Np. The synthesis and properties of neptunium metal, alloys, and intermetallic compounds are introduced. The lecture describes neptunium compound synthesis, with resulting thermodynamic and structural properties provided. Neptunium organometallic and coordination compounds are also presented. Information on neptunium solution speciation, redox, and spectroscopy is given, with trends based on oxidation state examined. A presentation of analytical methods useful in neptunium chemistry, including Mössbauer spectroscopy, concludes the lecture. Comparisons are made with uranium chemistry to provide trends in the actinides. The lecture length is 26 minutes.
The lecture is assigned on Sunday 17 February 2019 and due Friday 22 February 2018. When you have completed the lecture please comment on the blog and respond to the Lecture 13 PDF quiz
