What does the name ytterbium mean?
A rare divalent or trivalent, silvery, soft, malleable, and ductile metallic rare-earth element.Ytterbium has little practical application. Number 70 in the Periodic Table of Elements, ytterbium is named for the village of Ytterby, Sweden, where it was discovered. So were erbium, yttrium, and terbium. See also erbium and television.
What is ytterbium’s normal phase?
Ytterbium exists in three allotropic (structural) forms. The α-phase, which exists below 7 °C (45 °F), is close-packed hexagonal with a = 3.8799 Å and c = 6.3859 Å at room temperature. The β-phase is face-centred cubic with a = 5.4848 Å, and it is the normal structure at room temperature.
Is ytterbium found on Earth?
Ytterbium is never found in nature as the free element. Ytterbium is found in the ore monazite sand [ (Ce, La, etc.)PO 4] and an ore containing small amounts of all the rare earth metals. It is also found in the ores euxenite and xenotime. It is difficult to separate from other rare earth elements.
What family does the element ytterbium belong to?
Ytterbium belongs to the lanthanide family. The lanthanides make up Row 6 of the periodic table. The periodic table is a chart that shows how the chemical elements are related to each other.
