Transition elements are elements in the periodic table that are located in the d-block. They are called transition elements because they are located between the s-block and the p-block. The transition elements are in the second and third transition series.
Oxidation states overview
An oxidation state is a number assigned to an atom in a molecule that indicates the degree of oxidation of that atom. atoms can have more than one oxidation state, and the oxidation state of a particular atom can change during a reaction.
The oxidation state of an atom is usually determined by the number of electrons that atom has lost or gained. For example, an atom that has lost two electrons has a oxidation state of +2, and an atom that has gained two electrons has a oxidation state of -2.
Stability of oxidation states
The oxidation state of an atom is determined by the number of electrons it has lost or gained. The most stable oxidation state is the one in which the atom has the fewest possible changes in its electron configuration.
Oxidation State of Transition Elements
The oxidation state of a transition element is the charge it has on its outermost electron shell. The oxidation state can be positive, negative, or zero.
Variable Oxidation State of Metals
Metals can exist in different oxidation states, which is a measure of how many electrons the metal has lost or gained. The oxidation state of a metal is shown as a Roman numeral after the metal’s name. For example, iron can exist in oxidation states of II, III, and IV.
The table below shows the oxidation states of some common metals.
