Ytterby
Ytterby (pronounced: [ˈʏ̂tːɛrˌbyː]) is a village in the Vaxholm municipality in Stockholm County, Sweden. It is known for the Ytterby quarry, the single richest source of elemental discoveries in the world, with four elements named after the village: Yttrium, Ytterbium, Terbium, and Erbium.
Etymology
The name "Ytterby" is derived from the Swedish words "ytter" meaning "outer" and "by" meaning "village". The village was likely named for its location on the outer edges of the Stockholm archipelago.
Ytterby Quarry
The Ytterby Quarry was a former mine that was the source of many rare earth elements. The quarry is now closed, but during its operation, it was the single richest source of elemental discoveries in the world. The elements Yttrium, Ytterbium, Terbium, and Erbium were all discovered in minerals from this quarry and named after the village of Ytterby.
Yttrium
Yttrium (pronounced: [ˈɪtrɪəm]) is a chemical element with the symbol Y and atomic number 39. It was discovered in 1794 by Finnish chemist Johan Gadolin from a mineral sample from the Ytterby quarry.
Ytterbium
Ytterbium (pronounced: [ˈɪtərbiəm]) is a chemical element with the symbol Yb and atomic number 70. It was discovered in 1878 by Swiss chemist Jean Charles Galissard de Marignac in a sample of what was later named "gadolinite" from Ytterby.
Terbium
Terbium (pronounced: [ˈtɜːrbiəm]) is a chemical element with the symbol Tb and atomic number 65. It was discovered in 1843 by Swedish chemist Carl Gustaf Mosander in a sample of what was later named "ytterbite" from Ytterby.
Erbium
Erbium (pronounced: [ˈɜːrbiəm]) is a chemical element with the symbol Er and atomic number 68. It was discovered in 1843 by Swedish chemist Carl Gustaf Mosander in a sample of what was later named "ytterbite" from Ytterby.
