Because lithium is extremely reactive and can undergo in air a violent oxidation.
LITHIUM!! It is a soft alkali metal with a silver-white color. Under standard conditions, it is the lightest metal and the least dense solid element. Like all alkali metals, lithium is highly reactive, corroding quickly in moist air to form a black tarnish. For this reason, lithium metal is typically stored under the cover of oil. When cut open, lithium exhibits a metallic lustre, but contact with oxygen quickly returns it back to a dull silvery grey color. Lithium is also highly flammable.
Any of the alkali metals: lithium, sodium, potassium, etc.
Potassium, and Ceasium. Maybe Lithium as well. Alkali earth metals anyway.
Sodium is an example of a metal that must be stored under water to prevent it from reacting with air or moisture. Sodium is highly reactive and can ignite spontaneously upon exposure to oxygen. Placing it under water helps to keep it stable.

Lithium is a metal, it looks silvery and is shiney when freshly cut but will tarnish quickly in air. It is the lightest metal and is normally stored under oil in airtight jars as its very reactive with water.
Lithium can be stored in materials such as mineral oil, kerosene, or naphtha to prevent contact with air or moisture. It is important to store lithium in an airtight container to avoid reactions with moisture or air that can lead to fire or explosion.
SOLID Under standard conditions Lithium is the lightest metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable. For this reason, it is typically stored in mineral oil.
Storing lithium metal in toluene is not recommended as it can react violently and produce flammable hydrogen gas. It is safer to store lithium metal under mineral oil or a non-reactive inert gas for stability.

Lithium is stored under oil to prevent it from reacting with moisture or air, which could lead to the formation of lithium hydroxide and release of hydrogen gas. The oil acts as a barrier to protect the lithium from these reactions and ensure its stability.
No, magnesium is not typically stored under oil. Magnesium is a reactive metal that can react with water and air, so it is usually stored under a dry and inert atmosphere like argon or mineral oil to prevent oxidation.
Oil-based ingredients typically include hydrocarbons such as alkanes, aromatics, and cycloalkanes. Other elements may include traces of sulfur, nitrogen, and oxygen compounds, depending on the type of oil and refining process.
Any of the alkali metals: lithium, sodium, potassium, etc.
Lithium is very reactive and a layer of compounds such as the oxide build up on the surface. This slows the initial reaction. Also, if the lithium is stored in oil and this is not removed it may keep the water away from the metal.
Potassium, and Ceasium. Maybe Lithium as well. Alkali earth metals anyway.
Lithium has a high luster when a solid sample of the pure metal is inspected. But it quickly tarnishes in air as it reacts with water vapor and other things. Lithium is quite reactive, and that makes its shine disappear quickly unless something is done to preserve it. Stored under an inert oil or in an inert gas atmosphere, it will retain its luster.
