Question

The positive oxidation number of $Xe$ is perxenate ion is eight.
If true enter 1, else enter 0.

• A. 1

Answer 1

The correct option is A 1
Let $x$ be the oxidation state of $Xe$ in perxenate ion (${Xe{O}_6}^{4-}$).

Since the overall charge on the complex is $-4$, the sum of oxidation states of all elements should be equal to $-4$.
Therefore,

$x+6(-2)=-4$
or, $x-12=-4$

or, $x=+8$

Thus, the positive oxidation number of $Xe$ is perxenate ion (${Xe{O}_6}^{4-}$) is eight.
