One Tiny Swedish Village Named Four Elements on the Periodic Table: The Geological Miracle of Ytterby
00:00 — The Feldspar Quarry Discovery
In 1787, Carl Axel Arrhenius discovered a heavy black rock in the Ytterby feldspar mine. Chemist Johan Gadolin analyzed the sample and isolated a completely new chemical oxide.
00:25 — Four Elements from One Island
Chemists derived Yttrium (Y), Terbium (Tb), Erbium (Er), and Ytterbium (Yb) directly from Ytterby’s name, and nearby cities Stockholm and Scandinavia inspired Holmium (Ho) and Scandium (Sc).
00:45 — Modern Uses of Rare Earth Lanthanides
Today, Yttrium is vital in high-temperature superconductors and lasers (Nd:YAG), while Terbium powers solid-state computer memory and green phosphors.

Did you know that a single, tiny Swedish village of barely 800 people has FOUR separate elements on the periodic table named after it? 1. Ytterbium (Yb), 2. Terbium (Tb), 3. Erbium (Er), 4. Yttrium (Y)... and they even almost named a fifth one!
Frequently Asked Questions (FAQ)
Which four elements are named after Ytterby?
Yttrium (Y, 39), Terbium (Tb, 65), Erbium (Er, 68), and Ytterbium (Yb, 70).
Are rare earth elements actually rare on Earth?
No. Most rare earth elements are relatively abundant in Earth’s crust (Cerium is more abundant than Copper), but they are rarely found in concentrated, easily mineable ore deposits.
Can the Ytterby mine still be visited?
Yes. The historic Ytterby mine is recognized as an international historical landmark by the European Chemical Society (EuChemS).
