Vedclass · Answer

(B) The lanthanoids are a series of $14$ elements from Cerium ($Ce$,$Z=58$) to Lutetium ($Lu$,$Z=71$).All lanthanoids exhibit a common oxidation state of $+3$ due to the loss of two $6s$ electrons and one $4f$ or $5d$ electron.While some elements show $+2$ or $+4$ oxidation states in specific compounds,$+3$ is the most stable and characteristic oxidation state for the entire series.

The common oxidation state of the elements of the lanthanoid series is .....
