Dysprosium is a rare earth element that has a metallic, bright silver luster, relatively stable in air at room temperature, but dissolving readily in dilute or concentrated mineral acid s with the emission of hydrogen.
Dysprosium was first identified in Paris in 1886 by France chemist Paul Émile Lecoq de Boisbaudran ; however, the element itself was not isolated in relatively pure form until after the development of ion exchange and metallographic reduction techniques in the 1950s.
Dysprosium is never encountered as the free element, but is found in many mineral s, including xenotime, fergusonite, gadolinite, euxenite, polycrase, blomstrandine, monazite and bastnasite, often with erbium and holmium or other rare earth elements.

 PERIODIC TABLE
Commercial sources of Dysprosium are bastnasite ore found in China and North America as well as the ionic clays found in Southern China, with the latter containing a greater percentage of the element at about 4-10%.
Dysprosium is commonly available in its lustrous metal form as well as its powdered oxide form.
Dysprosium metal is used in permanent magnets for use in audio speakers and industrial applications as well as for magnetorestricitive alloys.

Cuprous iodide is prepared in the laboratory by reacting pellets of copper metal with boiling 47% hydriodic acid.
Gallium iodide can now be obtained from commercial vendors, but several years ago gallium chloride was the only halide salt available commercially, and it was necessary to convert it to iodide.
Lithium chloride, lithium bromide, lithium iodide, and mixtures of the bromide or chloride with lithium metal have been used as charge material for the separation of the isotopes of lithium.

This study was conducted at Argonne National Laboratory, in the early 1950s, to test and calibrate a sodium iodide scintillation counter.
Three individuals ingested a few microcuries of sodium-24 (Na24) and the sodium iodide scintillation counter apparatus was used to determine the gamma-ray activity of Na24 in the subjects.
Each volunteer was given an oral dose of liquid containing 8 microcuries of I131 as sodium iodide, then measured for whole body and thyroid content of I131 within 1 hour.
