Certain newspapers need to catch up on the technical details:
contain as much gold, platinum and rare earth metals – such as rhodium
Rhodium isn\’t a rare earth metal. It\’s a platinum group metal.

Probably because if you point a journalist to a periodic table they will probably still giggle at the word ‘period’ in the name…
more on exotic metals please 🙂
There was some mong in the comments in the Torygraph saying that yttrium wasn’t a rare earth; that rare earths comprised lanthanides and actinides. I pointed out that uranium is not a rare earth and to stop being a prat.
(conventionally, rare earths = lanthanides + Y + Sc. Seventeen elements in all.)
