Spring 2016: CHEM 312 Lecture 13 Neptunium Chemistry

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.

  2. I finished the lecture and the quiz. Looking at its applications, Np is pretty interesting as a radiotracer for reactions and as a heat source for radioisotope thermoelectric generators.

  6. Just finished the lecture and quiz. I found quantitative analysis (basic acid/base rxns) fairly boring before learning about the actinides. Much more interesting now!
