Why K and Na are kept in kerosene?

K and Na are kept in kerosene to prevent them from reacting with oxygen and moisture in the air, which would quickly tarnish their surfaces. Kerosene forms a protective layer that helps to maintain the reactivity and appearance of these reactive metals.


Why is sodium kept under kerosene?

The kerosene molecule does NOT have any oxygen atoms in the molecule; it is an hydrocarbon. Sodium metal will readily react with oxygen, be it in a molecule ( water) or the atmosphere ( atmospheric oxygen in the air). Hence to keep it away from oxygen, it is kept under kerosene. as are all the other Group(1) [alkali] metals.


What metals softer and more reactive than other metals?

Potassium, sodium, and lithium are softer and more reactive than other metals. They are typically stored in oil or kerosene to prevent them from reacting with moisture in the air.


How chemically active are alkali metals?

Alkali metals are the most reactive metals.


What are more reactive alkali metals or alkline earth metals?

alkali metals


How are alkali metals different any from other metals?

Alkali metals are very reactive metals.


Is alkali the only earth metal?

No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.


Why are alkali metals stored in oil and kerosene?

They are so reactive they even react with the moisture in the air. Storing under oil prevents this.


How do alkali metals react with other alkali metals?

They don't


Why are earth alkali metals called earth alkali metals?

Alkali earth metals are named after their oxides, alkaline earth.


What are the group of soft silvery reactive metals known as?

alkali metals


Is a coin an alkali?

No, a coin is not an alkali. It's a metal or metal alloy. Alkali metals are very reactive and coins are not made of them. These metals react with the water in air, so they are stored beneath a liquid they do not react with (like kerosene), or in a gas they will not react with (like an inert gas). Making coins out of alkali metals would give entirely new meanings to "depreciation" and the phrase "money burns a hole in my pocket."
