Starting with the Rare Earths
I would like to start doing chemistry with some of the lanthanides (rare earth metals, I mean), but I want to know with which metals should I begin
doing this chemistry. A friend of mine told me ytterbium was interesting to start with...
Which salts should I buy? Any ideas for interesting experiments (and preferably a bit easy?)?
Thanks!!

neodymium compounds and their amazing ability to change color depending on light source.
That's all I can think of...

Easiest / commonest one that comes to mind... cerium. Might as well start with that one.
And maybe you could make some cerium (IV) ammonium nitrate... nice bright colored compound, useful in analysis.

Thanks for the help! Any properties of the salts that may be interesting to see?

Several of the rare earth elements have interesting fluorescence properties. Terfenol-D is an interesting rare earth alloy that expands in a magnetic
field. Ytterbium is used as a detector for earthquakes and other high stresses because it changes resistance.

Try extracting the neodymium from neo magnets, very hands on and quite satisfying, not to mention quite cheap to do. A long thread on that here:

Dysprosium salts are paramagnetic!

Indeed. Here's a short video showing paramagnetism in Dysprosium sulphate.

Sorry
to dig up an old thread, but when I first read this, I thought it sounded a little sensational. Perhaps a clarification is in order:<a
href="http://en.wikipedia.org/wiki/Ytterbium#Others" target="_blank"> | Quote: | | Ytterbium metal increases its electrical resistivity when subjected to high stresses. This property is used in stress gauges to monitor ground
deformations from earthquakes and explosions. <img src="../scipics/_wiki.png" /> |

I’ve used praseodymium oxide as a pale yellow paint pigment. You might try making the chloride or nitrate. Here in the States, we have a ceramic
pigment supplier that goes by the name USPigment. They are based in Illinois and have 14 or 15 rare earth oxides at reasonable prices. They are
least good enough for pigments so making their salts should not require a ton of purification work up.

A magnetic salt? awesome.

there are so many better yellow pigments.. where do they even get praseodymium
