'S e meatailt bog agus lantanach a tha ann.

Eachdraidh

Ann an 1878 lorg Jean Charles Galissard de Marignac ogsaid ùr ann an gadolinit agus dh'ainmich e am meatailt "iterbium" air Ytterby san t-Suain.Ann an 1907 lorg Georges Urbain san Fhraing,[2] Carl Auer von Welsbach san Ostair,[3] agus Charles James sna Stàitean Aonaichte[4] gun robh dà eileamaid anns an ogsaid seo.

Dh'ainmich Urbain iad neoiterbium agus lutecium (lutetium an-diugh) agus von Welsbach iad aldebaranium is cassiopeium air an reul agus air an reul-bhad.Rogh an Coimisean Eadar-naiseanta air Tomadan Atamach na h-ainmean Urbain (seach iterbium an àite neoiterbium) agus thug iad prìomhachas dha.

Cleachdadh

Cleachdar iterbium-169 mar bun-gathan-gamma airson rèidiografaidh.
