Which of the following oxidation states is common for all lanthanides?

A
\( +2 \)
Correct answer
B
\( +3 \)
C
\( +4 \)
D
\( +5 \)

Solution

Lanthanoids exhibit \( +3 \) oxidation states as the most stable configuration is acquired on losing \( 3 e^{-} s \).

Hence, the correct answer is option: 'B'.
