Erbium oxide is used in ceramics to obtain a pink glaze. Also a few uses in the nuclear industry and as an alloying agent for other exotic metals. For example, it increases the malleability of vanadium. Found with other heavier rare earths in xenotime and euxerite. E-DY_RT4fJ4 Erbium
Xenon was discovered in England by the Scottish chemist William Ramsay and English chemist Morris Travers in 1898.

They found xenon in the residue left over from evaporating components of liquid air.

Spectroscopic analysis showed the previously unseen beautiful blue lines that indicated the presence of a new element. From the Greek word xenon, stranger 68 1842 Carl G. Mosander Sweden Named after the village of "Ytterby" near Vaxholm in Sweden

Xenon je netoxický, ale jeho sloučeniny jsou vysoce toxické
If inhaled, xenon can cause a person's voice to deepen
Xenon is used in flash lamps and arc lamps, and in photographic flashes.

Xenon is used in medicine as a general anesthetic and in medical imaging.

In nuclear energy applications, xenon is used in bubble chambers, probes, and in other areas where a high molecular weight and inert nature is desirable.
