One funnel of yttrium contains exactly the same number of atoms as is contained in a gaseous atom of nitrogen.
Its group members, scandium and yttrium, have the same form; we have not examined the fourth; the group is positive.
yttrium was obtained by Whler in 1828, as a brittle, dark-grey metal, made from the chloride by the action of sodium.
In yttrium, on the proto level, a 110 and b 63 both escape from the funnel, and behave as in scandium.
Erbium, a rare metal found along with yttrium, terbium, and other rare elements in some rare minerals.
Nitrogen has nothing new to show us, all its constituents having appeared in scandium and yttrium.
A rare metal found by Prof. Mosander, associated with erbium and yttrium in ordinary yttria.
metallic rare-earth element, 1866, coined in Modern Latin by Swedish chemist Carl Gustaf Mosander (1797-1858) from Ytterby, name of a town in Sweden where mineral containing it was found.
yttrium yt·tri·um (ĭt'rē-əm)
A silvery, ductile, rare-earth element used in various alloys. Atomic number 39; atomic weight 88.905; melting point 1,522°C; boiling point 3,338°C; specific gravity 4.47 (25°C); valence 3.
A silvery metallic element found in the same ores as elements of the lanthanide series. Yttrium is used to strengthen magnesium and aluminum alloys, to provide the red color in color televisions, and as a component of various optical and electronic devices. Atomic number 39; atomic weight 88.906; melting point 1,522°C; boiling point 3,338°C; specific gravity 4.45 (25°C); valence 3. See Periodic Table.
