Group 1 metals are stored under oil because they are so reactive, they will react with the oxygen in the air if you leave them unprotected, but will also react with water, therefore they need to be stored in oil.

∙ 11y agoSodium (Na), Potassium (K), Rubidium (Rb) and Cesium (Cs) are stored under oil because they are so reactive they will react with the oxygen and moisture in air very quickly. They quickly become covered with a crust of the compounds and thus no longer metal but compounds and salts. They are stored under oil until they are needed.

∙ 11y agoSodium metal is EXTREMELY reactive with air and water, so they put it in oil to keep it from doing that.

∙ 13y agoThe alkali metals are stored under oil as they will react with air and moisture if they make contact with it, ruining the sample and even posing a fire hazard.

Why is sodium not stored in petrol?
Sodium metal IS stored in petrol, or more commonly is kerosene or oil.
Why potassium metal stored in kerosene oil?
Because in air potassium is easy oxidized.
Why are sodium and potassium stored in kerosene oil not in another oil?
It is important that the oil for storage of these metals be very water-resistant, and that it not have a high vapour pressure. It must not react with the metal. It is also nice if a storage oil is relatively non viscous and non-sticky so that the oil can be easily removed when the metal is needed. Being cheap also helps. Kerosene is the oil that best meets these requirements.
Where can you store sodium metal?
Because sodium is so reactive, it will react with air to form oxides. Therefore, it is stored under oil in order to protect it from oxidation.
What all can lithium be stored in?
Lithium is stored in mineral oil to protect it from air and moisture.
How is the metal sodium stored?
it can b stored in oil
What material are stored in metal with cover?
cooking oil and gasoline
Why is sodium not stored in petrol?
Sodium metal IS stored in petrol, or more commonly is kerosene or oil.
How is potassium stored?
The pure metal must be stored under oil to protect it from oxygen and water vapor in the air.
How should sodium be stored?
If you buy sodium metal, it's packed in either oil or argon. That's how it's stored.
Why is potassium metal stored in kerosene oil?
Because in air potassium is easy oxidized.
Why potassium metal stored in kerosene oil?
Because in air potassium is easy oxidized.
Which metal is kept under water?
I dont think there is a metal stored under water because they react with water and instead are stored in kerosene or oil. Water often corrodes the metal producing rust so i cant think of any metal that would be stored under water.
Why lithium metal is stored under oil?
Because lithium is extremely reactive and can undergo in air a violent oxidation.
Is sodium metal kept in oil for safe storage but reacts violently with water?
it is stored in metal to stop it from wearing away and it does act violently with water, but not to bad
Is radium stored in oil?
Radium is not stored in oil.
What is the state of potassiun?
Potassium is a metal at normal temperatures. It has to be stored under oil otherwise it will react with oxygen in the atmosphere, possibly dangerously.
