Question

in the first transition series of element which element show higher Oxidation State​

Answer 1

Answer:

I think so this is a answer -

Scandium is one of the two elements in the first transition metal period which has only one oxidation state (zinc is the other, with an oxidation state of +2). All the other elements have at least two different oxidation states.

Answer 2

Explanation:

Manganese which lies in the middle of the period has the highest number or oxidation state and thus the highest oxidation state in the whole period since it has 5 unpaired electrons.
