Why are samples of the alkali metal cesium usually stored in argon acid?

Answer 1

Most often to provide a chemically inert atmosphere in which a reaction can take place. Argon is preferred over the lighter noble gases for this purpose because argon is denser than air. And to make Pizza!!! :)

Answer 2

The chemical properties of cesium are extremely reactive and pyrophoric (much like rubidium and potassium). As a result, any contact with water can result in a nearly explosive reaction. Argon is a noble gas, and chemically stable under most conditions and forms no known stable compounds under normal conditions. Submerging cesium in argon makes it relatively safer to handle.

Answer 3

Caesium is very reactive. It is the least electronegative all all elements and ignites spontaneously in air, reacts violently with water at below -100 deg C. One way to store it is in the inert gas, Argon.

Answer 4

Because argon is much less reactive than air, especially than the oxygen in the air. Many reactive chemicals would react (corrode or even burn or explode) if exposed to contact with oxygen.

Answer 5

Argon is a noble gas with its outer valence completely filled. This makes it non-reactive, so anything placed inside will not have anything to react with.

Answer 6

Argon is a noble gas and therefore virtually nonreactive.

Answer 7

Because it is highly volatile and explodes when comes into contact with water etc.

Answer 8

The noble gasses are all pretty nonreactive it takes a lot to get them to react with things, so storing things with argon would prevent it from reacting.

Answer 9

Because caesium is highly reactive. An environment of an inert gas, such as argon, protects it from chemical reaction.

Answer 10

Caesium is highly reactive and, if left in air would oxidise. However, argon is an inert gas and caesium stored in an atmosphere of argon has nothing that it can react with.
