Chapter 23, Problem 23.18P

Interpretation Introduction

Interpretation:

The transition metals that have a maximum oxidation state of $+6$ has to be given.

Concept introduction:

Oxidation number: (Oxidation state) A number equal to the magnitude of the charge an atom would have if its shared electrons were transferred to the atom that attracts them more strongly.

Groups $\text{3B}\left(\text{3}\right)\text{ to 7B}\left(\text{7}\right)\text{,}$ the highest oxidation state is equal to the group number.  The highest oxidation state occurs when both $ns$ electrons and all $\left(\text{n–1}\right)\text{d}$ electrons have been removed.
