WHOA, BACK DAFUQ UP MAN! YOU DON'T MESS WITH A HAZARD TO LANTHANIDES LIKE THAT!

There are lots of interesting things that lanthanides do which no other elements do. In particular there are plenty of fluorescent and magnetic lanthanide compounds, most of which are simple salts (terbium sulfate).

As metals they're also quite different. It's easy to tell apart the brassy ytterbium from the quickly-corroding europium. Both of which, I might add, have interesting redox chemistry.




At the end of the day, simulating atoms doesn't beat working with the real things...

and they are famous for lanthanide contraction

@Brain, you are a bit biased about that by any chance :)

I quite like niobium, it's got a lot of cool applications due to it's resistance to chemical attack, it has some space in the catalysis field (I know a guy who's worked on catalysis of ethanol reform using niobium compounds), it is used in the production of superconductors and there are a lot of fancy alloys made with it.If only it didn't cost so freaking much :(

But then I have never actually seen it and haven't heard of any applications so what do I know. For all I know it might form a salt that is superconductive to light and has zero opacity.)


(and others claiming lutetium is boring)

Lutetium is used in the form of lutetium yttrium oxyorthosilicate as a high performance scintillator crystal, with its principal application being in PET (positron emission tomography) scanners. If you ever undergo a PET scan, you are making use of lutetium. :)

Samarium and cerium both have useful chemical properties not shared with the other lanthanides. Terbium is crucial to magnetostrictive alloys (terfenol). Gadolinium is weirdly ferromagnetic. Yttrium (not a real lanthanide) forms a hydride under mild conditions.
