Detailed Solution

Oxygen or fluorine can oxidise the metal to its greatest oxidation state due to its tiny size and high electronegativity.

Due to the fact that fluorine and oxygen are the most electronegative elements, the highest oxidation state of a metal can only be seen in its oxide or fluoride form. Any transition element will exhibit a maximum oxidation state of +8.
