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.
Predominantly, the transition elements, but also hydrogen, nitrogen, and oxygen. Actually all elements that have reactions can have more than one oxidation number in the sense that their oxidation number is 0 when they are in pure form and usually is some other value when they are in compounds.
To find the oxidation number of an element using the periodic table, you need to consider the group number for main group elements and the charge on transition metals. Main group elements typically have oxidation numbers equal to their group number, while transition metals can have multiple oxidation states indicated by Roman numerals in parentheses. Exceptions like oxygen (-2) and hydrogen (+1) exist, and the sum of oxidation numbers in a compound must equal zero.
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.
The maximum oxidation number is theoretically equal to the number of valence electrons. For example the oxidation number of chlorine among different compounds can vary from -1 to +7. An exception for this is fluorine, which only have -1 and 0 as its oxidation numbers.
Transition metals, such as iron, copper, and chromium, are known for having elements that can exhibit more than one oxidation number. This is due to the presence of partially filled d orbitals in their electron configuration, allowing them to lose or gain electrons in different ways.
Most elements can have more than one oxidation number, but I think you are looking for the transition elements in groups 3 - 12.

The Roman numeral in the parentheses is the valence or oxidation of the metal that it follows. Transition elements have more than one oxidation number
Sc and Zn are not classified as transition metals. They does not have stable different oxidation numbers.

Group 1 elements have an oxidation number of +1, group 2 elements have an oxidation number of +2, group 17 elements have an oxidation number of -1, and group 18 elements (noble gases) have zero oxidation number since they are chemically unreactive.
Elements that have a single oxidation number include group 1 elements (e.g. sodium, potassium) which have an oxidation number of +1, and group 2 elements (e.g. magnesium, calcium) which have an oxidation number of +2.
Group 1 elements have an oxidation number of +1.
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.
