    How is the variability in oxidation state of transition metals different from these of p-block elements ?

    In which pair highest oxidation states of transition metals are found

    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

    Statement-1: the highest oxidation state of transition metal is exhibited in its oxide or fluoride only. Statement-2: Small size and high electronegativity of O and F can oxidise the metal to its highest oxidation state.
