Since the transition metals have the electronic configuration of 4s2 3dn, and so the 4s2 electrons have similar energy levels to the 3dn and so its easier to loose them to change to the +2 oxidation state. Fe, for example:
Fe [Ar] 3d64s2 Fe2+ [Ar] 3d6 Fe3+ [Ar] 3d5
The highest oxidation state of a transition metal is typically found in group 7b (Mn, Tc, Re) elements, reaching up to +7 oxidation state.
Preferably in modern nomenclature, by capital "Roman numerals" within parentheses immediately following the name of a transition metal element cation in a chemical compound. For transition metal elements that have only two common cationic oxidation states, the oxidation states can alternatively be indicated by the suffix "ic" for the more positive oxidation state and "ous" for the less positive ones. Examples are "ferric" for "iron (III)" and "ferrous" for "iron (II)". If the transition metal is in an anion, the most common indication is with suffixes and prefixes, but the appended oxidation state in parentheses can also be used. Details may be different for different transition metals and should be sought in an authoritative reference source.
+2
Transition metals contain atoms that form colored ions and have more than one positive oxidation state. Examples include chromium, manganese, iron, cobalt, copper, and nickel.
The most common oxidation state of -2 would be Oxygen.
The oxidation number of transition elements can vary because they have multiple oxidation states. Transition metals typically exhibit more than one oxidation state due to the presence of partially filled d orbitals, allowing them to lose a variable number of electrons. Common oxidation states for transition elements range from +1 to +7.
The highest oxidation state of a transition metal is typically found in group 7b (Mn, Tc, Re) elements, reaching up to +7 oxidation state.
M2+ ions are common for transition elements because they involve the loss of two electrons from the outermost d orbital, leading to a stable configuration. Transition metals have partially filled d orbitals and can easily lose two electrons to achieve stability in the +2 oxidation state. This makes M2+ ions a common oxidation state for transition elements.
The subscript of the second ion identifies the oxidation state of the transition metal
Transition elements are the elements found in the d-block of the periodic table, located between groups 3 and 12. They have partially filled d orbitals and exhibit a wide range of oxidation states. Transition elements typically show metallic properties and are characterized by their ability to form colored compounds.
No, Pb is not a transition metal and it has 2 oxidation states
Elements in group 2 mostly takes the oxidation number +II.
Transition elements can exhibit a variety of oxidation states, typically ranging from +1 to +7. The maximum oxidation state is often associated with the element's ability to lose all its valence electrons, including those from the d-orbitals. For example, manganese (Mn) can reach an oxidation state of +7, while chromium (Cr) can achieve +6. The specific maximum oxidation state varies among different transition metals due to their unique electron configurations and chemical properties.

A pure metal has the oxidation state zero.
The oxidation state of a transition metal is determined by the number of electrons it has lost, gained, or shared when forming compounds. This is typically indicated in the compound's formula by using Roman numerals to denote the oxidation state, such as in iron (III) oxide (Fe₂O₃), where iron has an oxidation state of +3. To identify the oxidation state, one can analyze the overall charge of the compound and the charges of the other elements involved, allowing for a systematic determination of the metal's oxidation state.
Transition metals typically use the Stock system for naming compounds with variable oxidation states. This system involves using Roman numerals in parentheses to indicate the oxidation state of the metal ion in the compound.
