Describe the trend in I.E., electrode potential, atomic radii and oxidation states of elements of first transition series.

Compare the stability of +2 oxidation state for the elements of the first transition series.

What is the most common oxidation state of first transition series?

The first ionisation energies of the elements of the transition series.

The first ionisation energies of the elements of the first transition series (TitoCu)

The most common oxidation states of 3d series elements

The atomic radii of transition elements in a period are.

What is the highest oxidation state shown by a transition element.

Regarding the oxidation states of elements of transition element the incorrect statement is

The atomic radii of transition elements from Cr to Cu are almost equal because

The transition element ( with few exceptions ) show a large number of oxidation states . The various oxidation states are related to the electronic configuration of their atoms. The variable oxidation states of a transition metal is due to the involvement of (n-1)d and outer ns electrons . For the first five elements of 3d transition series , the minimum oxidation state is equal to the number of electrons in 4s shell and the maximum oxidation state is equal to the sum of 4s and 3d electrons. The relative stability of various oxidation states of a given element can be explained on the basis of stability of d^(0),d^(5) and d^(10) configuration . In 3d series, the maximum oxidation state is shown by
