# Name a transition element which has no variable oxidation state?

Jun 23, 2018

I can't think of one offhand mate....

#### Explanation:

The transition elements, generally have several oxidation states available. For the first transition series, $M \left(+ I I\right)$ and $M \left(+ I I I\right)$ salts are widespread....

The f-block elements, and Group 3 of the transition series, are GENERALLY $M \left(+ I I I\right)$, however, even here, $M \left(0\right)$, $M \left(+ I\right)$, and $M \left(+ I I\right)$ salts and complexes are accessible, even if special means have to be employed to synthesize and isolate them...
