What does yttrium mean?
Yttrium is a chemical element with the symbol Y and atomic number 39. In its elemental form, it is a silvery metal, but most practical uses involve yttrium compounds or yttrium-containing materials. These occur in ceramics, phosphors, superconducting devices, and laser crystals, including yttrium aluminium garnet, commonly abbreviated YAG. In scientific prose, the word generally denotes the element as a mass noun, as in a statement that a sample contained yttrium. It may also refer to a particular atom or ion when discussing isotopes, radiation, or chemical reactions. The name comes from Ytterby, a village in Sweden where an important mineral containing several rare elements was found during the late eighteenth century. Yttrium is not a general-purpose synonym for another material; its meaning is specific to a distinct chemical element and is therefore chiefly encountered in technical and educational contexts.
nounYttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery metal used in ceramics, phosphors, superconductors, and laser materials.
- The chemical element yttrium, a silvery metallic element with the symbol Y and atomic number 39.
- An atom or ion of the element yttrium, especially in chemistry or nuclear physics.
"The laser uses a synthetic crystal of yttrium aluminium garnet, commonly known as YAG."
"The detector measured radiation from a sample containing yttrium."
"Yttrium isotopes can be produced for specialized scientific and industrial applications."
The plural 'yttriums' is not normally used when the word refers to the chemical element or a quantity of its material.
"The alloy contained yttrium together with zirconium and other metals."
Four element names—yttrium, ytterbium, terbium, and erbium—preserve the name of the little Swedish village where their mineral discoveries began.

Etymology of yttrium
The name yttrium derives from Ytterby, the Swedish village where the mineral gadolinite was found and investigated in the late eighteenth century. Anders Gustaf Ekeberg coined the name in 1794 for a newly identified element associated with the mineral from Ytterby. Ytterbium, terbium, and erbium were also named after the same village, making Ytterby an unusually important place in the history of chemical nomenclature.
How yttrium is actually used
Yttrium is chiefly a technical term in chemistry, materials science, physics, and related fields. In general prose it normally functions as a mass noun when referring to the element or its material, so a distinct plural is not normally used.
Easily confused with yttrium
Yttrium is element 39 with the symbol Y, whereas ytterbium is element 70 with the symbol Yb; both names ultimately refer to the Swedish village of Ytterby.
