sodium lithium
Alkali metals are often stored under oil.
Lithium, Sodium, Potassium, Rubidium, Caesium, Strontium and Barium. Let's exclude Francium and Radium shall we as they are radioactive and wont be around for long.
Sodium metal is highly reactive towards water or moisture in air so it is kept in organic oil.
Sodium, Potassium, Cesium, Francium
Alkali metals are often stored under oil.
sodium
The pure metal must be stored under oil to protect it from oxygen and water vapor in the air.
Nope. Sodium reacts violently with water. The pure stuff is normally stored under oil.
it can b stored in oil
They are stored in a jar of oil to prevent them from reacting, other wise they will start reacting with the surrounding air. :D
Cesium (Cs) itself does not have an odor, but if you smell something odd, it may be from the mineral oil that it's been stored in. Cesium is the most electropositive of all metals and must be stored under oil, because if it comes in contact with water or moist air, it ignites spontaneously with a reddish-violet flame.
group 1 elements are stored in oil because they are highly reactive elements.
the 7A family in the peroid table of elements
Lithium is stored in mineral oil to protect it from air and moisture.
Gggtgggrhghr
Potassium is chemically very active. It will react with oxygen and/or water vapor in the air, so it is stored under oil to keep it out of contact with the air. It doesn't react with the oil.
Group 1 metals are stored under a layer of oil. This prevents them from coming into contact with the oxygen in the air. Thus the violent reaction of group 1 metals and oxygen is prevented and the metals can be stored safely under oil.
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.
under ground in tanks so it doesnt ignite
The pure metal must be stored under oil to protect it from oxygen and water vapor in the air.
as it reacts with the oxygen in the air
They are so reactive they even react with the moisture in the air. Storing under oil prevents this.
Radium is not stored in oil.
