In 1794, Johann Gadolin of Finland discovered a new oxide in a mineral from Ytterby near Stockholm, Sweden, which he named ytterbia after the place of origin. Various elements, including yttrium, were found in ytterbia, and in 1878 Jean Charles Galissard de Marignac of Switzerland discovered a new element, which he named ytterbium.

Periodic table Element symbol = Y Atomic number = 39 Atomic weight = 88.9059 Abundance in the earth's crust = 33 ppm (26th place) Stable nuclide abundance ratio 89 Y = 100% Melting point = 1495 °C Boiling point = 2927 °C Specific gravity = 4.45 Electron configuration = [Kr] 4d 1 5s 2 Main oxidation number = III A rare earth element belonging to group IIIA of the periodic table. In 1794, Johann Gadolin of Finland discovered a new oxide in a mineral from Ytterby near Stockholm, Sweden, and named it ytterbia after the place of origin, but later it came to be called yttria (meaning the oxide of yttrium). In 1843, Carl Gustav Mosander of Sweden succeeded in separating yttrium into its three components (yttria, terbia, and erbia), retaining the old name yttrium for the element derived from one of the elements, yttrium, and giving the names terbium and erbium to the elements derived from terbia and erbia, respectively.
