Phosphorus.
Yes, very. from another wikianswers post: burns in exposure to air and it has to be stored under water
it is stored under water because to avoid it from igniting when it comes in contact with the air.
because it is highly reactive in nature & hence is stored under water
Red phosphorusis not stored under either water or oil. It is rather safe, although friction can convert it towhite phosphorus. Red phosphorus is used in some matches.It is white phosphorus that is the real nasty one. That is stored under water. White phosphorus ignites spontaneously in contact with air. That is the element used in some military munitions.
Because it is not connected to the sea water. It is stored as under ground water
groundwater reserves stored in aquifers.
Potato
Yes, elements with variable valency can be stored in water. However, the reactivity of the element will determine how stable it is in water. Some elements may react with water to form oxides or hydroxides, while others may remain stable. It is important to consider the specific properties of the element in question when storing it in water.
No. Potassium will react violently on contact with water. Potassium is stored under oil to protect it from air and water.
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.
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.
Sodium is a non-metal element that is kept under water because it reacts violently with moisture in the air, which can lead to fires or explosions. Placing sodium under water prevents it from coming into contact with air and ensures its safe storage.
