Yes, oil can protect metal from oxidation by creating a barrier that prevents moisture and oxygen from coming into contact with the metal surface. This protective layer reduces the likelihood of corrosion and rust formation. However, the effectiveness of oil as a protective agent depends on factors such as the type of oil used and the conditions to which the metal is exposed. Regular reapplication may be necessary to maintain protection.
Lithium metal is stored under oil to prevent it from reacting with moisture and oxygen in the air, which can cause it to degrade or ignite. The oil creates a barrier to protect the lithium surface from these reactions.
Oil protects metal from tarnishing by forming a barrier that prevents moisture and oxygen from reaching the surface. This barrier reduces the likelihood of chemical reactions that lead to oxidation and corrosion, which are the primary causes of tarnishing. Additionally, the oil can help repel contaminants and pollutants that might otherwise contribute to the tarnishing process, thereby prolonging the metal's appearance and integrity.
A pure metal has the oxidation state zero.
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.
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.

Oxidation of lubricating oil is primarily caused by exposure to oxygen in the air, high temperatures, and contaminants such as water and metal particles. These factors can lead to the formation of harmful byproducts that can degrade the oil and reduce its lubricating properties. Regular oil analysis and maintenance can help monitor and prevent oxidation in lubricating oil.
The function of the oil is to protect from metal to metal contact. The oil will eventually shear and break down. This will then allow for metal to metal contact. If there is metal to metal contact, your engine temp. will increase and can warp parts, therefore permanently lowering efficiency of the engine ( and fuel), and or lead to more costly engine failures. If you have trouble remembering to change your oil regularly, I reccommend using a synthetic oil. Synthetics protect better and increase your oil change intervals.
When the metal can exist in more than one oxidation state
Of course, it is not actually frost. It is oxidation. Use a good non-abrasive bore cleaner and once clean, use a light protective oil to protect the metal.
To effectively oxidize metal, you can expose it to oxygen in the air or use chemicals like acids to promote oxidation. This process creates a layer of oxide on the metal surface, which can protect it from further corrosion.
A pure metal has the oxidation state zero.
Rust is formed as a result of oxidation of iron (Fe) metal.
