Why are scandium and yttrium considered as rare earths?

And also phosphates in people, especially people with kidney problems.

I love how the views go down the further you get.

There is also a superconducting compound containing lanthanum and iron (!): LaO1-xFxFeAs. The x denotes the doping of flourine, which alters the superconducting properties.

[sounduser]

Its used to bind phosphates in aquariums

What was the rhyme again? Does anyone know when Lanthanum was added to the periodic table.

No.
