Which element show highest oxidation state in actinoid

Explanation

To determine which element shows the highest oxidation state in the actinoids, we can follow these steps:

### Step 1: Understand the Actinoids
The actinoids are a series of elements in the periodic table that range from actinium (Ac) to lawrencium (Lr). They include elements such as thorium (Th), uranium (U), neptunium (Np), and plutonium (Pu).

**Hint:** Look at the periodic table to identify the actinoid series and their positions.
