Elemental Tile

Thulium

Thulium is an easily workable metal with a bright silvery-grey lustre, is soft and tarnishes in the air. Despite its rarity, thulium is used as the radiation source in portable X-ray devices and in solid-state lasers. It has no significant biological role and is not particularly toxic.

1879 by Per Theodore Cleve, Sweden.

DISCOVERY

From the name of Thule, an ancient name of Scandinavia.
