Explain :Transition elements exhibit variable oxidation states.

Transition elements exhibit a large number of oxidation states.Explain.

Name a transition element which does not exhibit variable oxidation states.

Give reasons: Transition metals show variable oxidation states.

Which of the following transition element exhibit the oxidation state of +8?

Why do transition elements show variable oxidation states ? Name the element showing maximum number of oxidation states among the first series of transition metals from Sc (Z = 21) to Zn (Z= 30).

Most of transition metals show variable oxidation states. Explain
