Question

Which transition metal shows a highest oxidation states?

Answer 1

Transition Metals

• Any element in the d-block of the periodic table, which encompasses groups $3$ to $12$, is referred to as a "transition metal" by many scientists.
• The elements which give the greatest number of oxidation states occur in or near the middle of the series.

Transition metal shows a higher oxidation state

• Manganese, for example, exhibits all the oxidation states from $+2$ to $+7$.
• Mn $(\mathrm{Z}=25)$ has the most unpaired electrons in the d subshell and shows a high oxidation state $+7$.
