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.

How do atom get an oxidation number?
The oxidation number of an atom is determined by the number of electrons it gains, loses, or shares when forming a chemical bond. The rules for assigning oxidation numbers are based on the electronegativity of the elements and the structure of the compound. Generally, less electronegative elements have more positive oxidation numbers, while more electronegative elements have more negative oxidation numbers.
Why do elements with positive oxidation number easily combined with those having a negative oxidation number?
Elements with positive oxidation numbers have excess electrons that they can share or transfer with elements having negative oxidation numbers that have electron deficiencies. This transfer or sharing of electrons allows the elements to achieve a more stable electron configuration, forming compounds through the formation of ionic or covalent bonds.
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.
Do all elements in a group have the same oxidation numbers?
No, not all elements in a group have the same oxidation numbers. The oxidation number of an element can vary depending on the compound it is a part of and the specific chemical bonds it forms. Group trends can provide some guidance on common oxidation states, but there are exceptions.
What group of elements can have more then 1 oxidation number?
Transition metals are a group of elements that can have multiple oxidation numbers due to the presence of incomplete d orbitals, allowing for electrons to be easily transferred between different oxidation states.

Can an element have more than one oxidation number?
Of course they can have.Many elements have several oxidation numbers.

Common oxidation states for transition elements range from +1 to +7.
What elements can have variable oxidation numbers are known as known as what group of elements?
Most elements can have more than one oxidation number, but I think you are looking for the transition elements in groups 3 - 12.

Transition metals are a group of elements that can have multiple oxidation numbers due to the presence of incomplete d orbitals, allowing for electrons to be easily transferred between different oxidation states.
Why some elements has more than one oxidation number?
Some elements can have more than one oxidation number because they have multiple ways of forming bonds with other elements, leading to different arrangements of electrons. The oxidation number indicates the charge an atom would have if the compound was ionic. Elements can have variable oxidation states based on the different ways they can lose or gain electrons in chemical reactions.
What do Roman Numerals represent in chemistry?
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
Where is the oxidation number in the periodic table?
The oxidation number is not specifically listed on the periodic table. Oxidation numbers are assigned based on rules and guidelines that depend on the chemical properties and bonding of each element. Different elements can have multiple oxidation states, which can vary depending on the compound or molecule in which they are found.
How do you know which oxidation to use in a bond when it has multiple oxidation numbers?
You can determine the correct oxidation number to use by balancing the overall charge of the compound. Additionally, consider the electronegativity of the elements involved in the bond to determine the more likely oxidation state. In some cases, experimental data or rules of thumb based on common oxidation states for specific elements may also help in deciding the correct oxidation number to use.
What is the oxidation number of C in HCOH?
The oxidation number of C in HCOH is +2. This is calculated by considering the overall charge of the molecule, which is zero, and assigning values to the other elements accordingly.
