Transition elements usually have more than one oxidation number. In different oxidation numbers, the ions show different colors. Some of the ranges: Cu from +1 to +2; Cr from +2 to +6; Ni from +2 to +3; Co from +2 to +3 and Mn from +2 to +7.
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.
To determine the oxidation number of a transition metal, you can consider its overall charge and the charges of other elements in the compound. You can also use the rules based on the charge of common ligands or coordination numbers in coordination compounds. Remember that transition metals can have variable oxidation states due to their ability to lose different numbers of electrons.
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.
Elements with oxidation numbers of +1 include elements in Group 1 of the periodic table, like hydrogen and sodium. Elements with oxidation numbers of -1 include elements in Group 17, like fluorine and chlorine.
There is at least one oxidation number shared by all the elements in a periodic table column, but some of the elements may have more than one oxidation number and some of these additional oxidation numbers may not be possible for all the elements in a column.

Some of the elements exhibiting variable oxidation numbers are carbon (+4, -4); oxygen and selenium (-2 to +6); nitrogen and phosphorus (-3 to +5) halogens (except fluorine) (-1 to +7) and most of the transition metals and f block elements.

Common examples include many nonmetals as sulfur which bears oxidation numbers varying from -2 to +6 in forming compounds. In oxychlorides, the oxidation number of chlorine atom(s) vary from -1 to +7. Many transition elements also bear different oxidation numbers. Copper has two ions: Copper(I) which is colorless and Copper(II) which is pale blue.
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.
For most elements, their highest attainable oxidation number is equal to the number of valence electrons. Examples are the maximum oxidation numbers for: sulfur is +6, phosphorus is +5 and chlorine is +7. Fluorine is an exception which bears oxidation numbers 0, -1/2 and -1.
Elements located in groups 4 - 12 in the modern periodic table are considered as transition elements. Transition elements should not be confused with the d-block elements which are from groups 3 - 12.
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
Cobalt is a transition metal. Its oxidation states are 2 (3).
