A salt of the metal. It could be an oxide but equally, it could be a halide, carbonate, suplhate or other salt.
A pure metal has the oxidation state zero.
In compounds, barium (Ba) typically has an oxidation state of +2, as it is an alkaline earth metal. In a chemical reaction where barium is a reactant and remains a part of the product, its oxidation state generally stays at +2 for both the reactant and product. However, it's essential to examine the specific compounds involved to confirm this, as complex interactions might alter its state in rare cases.
No, Pb is not a transition metal and it has 2 oxidation states
A metal and a nonmetal would form an ionic bond. In an ionic compound, a metal ion would have a positive oxidation number equal to its ionic charge. A nonmetal would have a negative oxidation number equal to its ionic charge.Examples:NaCl oxidation numbers: sodium has an oxidation number of +1, chloride has an oxidation number of -1. So the overall charge of NaCl is zero.CaCl2 oxidation numbers: calcium has an oxidation number of +2, the chloride ion has an oxidation of -1. Since there are two chloride ions, the total negative oxidation number is -2, so CaCl2 has an overall charge of zero.
The oxidation state of a metal is indicated in the name of a compound if and when that metal has more than one oxidation states. The oxidation state is then indicated by a Roman numeral placed in parenthesis next to the metal (Stock System).
The end product of oxidation depends on the substance undergoing oxidation. For example, the end product of oxidation of organic compounds can be carbon dioxide and water, while the oxidation of metals can result in metal oxides. In biological systems, the end product of oxidation of glucose is carbon dioxide and water, which releases energy in the form of ATP.
When the metal can exist in more than one oxidation state
A pure metal has the oxidation state zero.
Oxidation on metal is caused by the reaction of metal with oxygen in the air, forming a layer of metal oxide on the surface. To prevent oxidation, metal can be coated with a protective layer such as paint, oil, or a metal coating like zinc or chrome. Keeping metal dry and storing it in a low-humidity environment can also help prevent oxidation.

Rust is formed as a result of oxidation of iron (Fe) metal.

A frozen pipe is a physical change, as it is just water changing state from liquid to solid (ice). However, a rusted metal bike is a chemical reaction as it is caused by the metal reacting with the oxygen in the air, in what is called an oxidation reaction.
Oxidation number of Li is +1. Oxidation number of oxygen is -2.
Zero The oxidation number of an element in its elemental form is always zero.
