Transition metals have variable oxidation numbers because they have incompletely filled d orbitals in their outermost electronic shell. These d orbitals can participate in bonding and easily change their oxidation states by gaining or losing electrons. This flexibility allows transition metals to exhibit a wide range of oxidation states in different compounds.

What is oxidation number of transition elements?
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.
What group has variable oxidation numbers?
Groups 1 and 2 are +1 and +2 respectivelly.. Group 3-12 have variable oxidation numbers - they are the so-called transition metals. Group 14-17 have variable oxidation numbers -even group 18- has- there are a number of different compounds of Xe for example. Group 1 and 2 have some strange compounds such as Cs11O3 . A better question might be which group doesn't have variable oxidation numbers!
How do you figure out oxidation number of a transition metal?
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.
How do transition metals properties compare with those of elements farther to the left?
The chemical reactivity of transition metals is generally less than that of metals to its left (group 1 and group 2 metals). However, transition metals can exhibit various oxidation states and hence form more number of compounds than group 1 and group 2 elements.
How can you determine an element's Oxidation number looking at a periodic table?
To determine an element's oxidation number on the periodic table, consider its group number (vertical column). Elements in Group 1 typically have an oxidation number of +1, Group 2 is +2, Group 7 (halogens) is typically -1, and Group 6 is often -2. Transition metals have variable oxidation states based on the compound. Remember that the oxidation number is the charge an atom would have if electrons were transferred completely.

Why do transition metals have multiple oxidation states?
Transition metals have multiple oxidation states due to the number of electrons that an atom loses, gains, or uses when joining another atom in compounds. It also determined the ability of an atom to reduce.

The chemical reactivity of transition metals is generally less than that of metals to its left (group 1 and group 2 metals). However, transition metals can exhibit various oxidation states and hence form more number of compounds than group 1 and group 2 elements.
Can transition metals have more than one oxidation number?
Yes, transition metals can have more than one oxidation number due to their ability to lose different numbers of electrons from their d and s orbitals. For example, iron can exist in the +2 and +3 oxidation states, while copper can be found in the +1 and +2 states. This variability in oxidation states is a key characteristic of transition metals and allows them to participate in a wide range of chemical reactions.
Do all metals have a number in parentheses?
Not all metals have a number in parentheses. The number in parentheses typically indicates the oxidation state of the metal in a compound, which is relevant for transition metals that can exhibit multiple oxidation states. However, many metals, especially those in groups like alkali and alkaline earth metals, commonly have a fixed oxidation state and may not require such notation.
How can you determine an element's Oxidation number looking at a periodic table?
To determine an element's oxidation number on the periodic table, consider its group number (vertical column). Elements in Group 1 typically have an oxidation number of +1, Group 2 is +2, Group 7 (halogens) is typically -1, and Group 6 is often -2. Transition metals have variable oxidation states based on the compound. Remember that the oxidation number is the charge an atom would have if electrons were transferred completely.
How do you find the oxidation number using the periodic table of elements?
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.
How many oxidation numbers in each group?
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.
Which family has elements that have more than one oxidation number?
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.
