CHEM 418 Nuclear Chemistry, Winter 2016: 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.  

The PDF Quiz for lecture 13 contains a signature box.  This is a new addition to the quizzes.

  1. I sent the lecture 12 and 13 pdf quiz as an attachment through email.
    I am interested in the different oxidation states and each has a particular color. Is the color of each oxidation states based on the charge-transfer transition?

    1. correct for the color. There are color changes with ligands that can also be used to determine speciation by UV-Visible spectroscopy.
