Question

Why is the highest oxidation state of a metal exhibited in its oxide or fluoride only? ​

Answer 1

Answer:

The highest oxidation state of a metal exhibited in its oxide or fluoride only since fluorine and oxygen are the most electronegative elements. The highest oxidation state shown by any transition element is +8.

Answer 2

$\huge \pink{question}$

Why is the highest oxidation state of a metal exhibited in its oxide or fluoride only?

$\huge \purple{answer}$

Both fluorine and oxygen have small size, high electronegativity and also high negative electron gain enthalpy. ... Thus, the highest oxidation states are shown in the oxides and fluorides of transition metals.
