Johan Gadolin was born in Åbo (Finnish name Turku), Finland (then a part of Sweden). [ 2 ] [ 3 ] Johan was the son of Jakob Gadolin , professor of physics and theology at Åbo. [ 4 ] Johan began to study mathematics at the Royal Academy of Turku ( Åbo Kungliga Akademi ) when he was fifteen.
It is composed of the first known rare-earth element, yttrium. [14] [7] [15] [16] Examining a different sample, Anders Gustaf Ekeberg confirmed the existence of a new "earth", calling it "yttria" and the source mineral "ytterbite". [7] The mineral that Arrhenius discovered and Gadolin and Ekeberg analyzed was eventually renamed gadolinite in ...
Yttrium is a chemical element; it has symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". [8] Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals and is never found in nature as a free ...
Ytterby is the single richest source of elemental discoveries in the world; the chemical elements yttrium (Y), terbium (Tb), erbium (Er), and ytterbium (Yb) are all named after Ytterby, and five more elements were also first discovered there. Local roads connect Ytterby to county road 274 and hence the mainland.

Klaproth independently discovered cerium (1803), a rare earth element, around the same time as Jöns Jacob Berzelius and Wilhelm Hisinger, in the winter of 1803. [17] William Gregor of Cornwall was the first to identify the element titanium in 1791, correctly concluding that he had found a new element in the ore ilmenite from the Menachan ...
Swedish chemist Carl Gustaf Mosander discovered terbium as a chemical element in 1843. He detected it as an impurity in yttrium oxide (Y 2 O 3). Yttrium and terbium, as well as erbium and ytterbium, are named after the village of Ytterby in Sweden. Terbium was not isolated in pure form until the advent of ion exchange techniques.
Mosander discovered lanthanum in 1838. This came from the Cerite-(Ce) from Bastnaes, Sweden, which at the time was the only abundant source for "Cerium", which had been discovered therein by Berzelius and Hisinger, and independently by Klaproth, in 1803.
