70 - Ytterbium lanthanide
Discovered by Jean de Marignac in 1878
- Atomic Radius (Å)
Ytterbium is a chemical element with symbol Yb and atomic number 70. It is the fourteenth and penultimate element in the lanthanide series, which is the basis of the relative stability of its +2 oxidation state. However, like the other lanthanides, its most common oxidation state is +3, seen in its oxide, halides and other compounds.
