Can inert gases be stored with oxidizing gases?

No, inert gases should not be stored with oxidizing gases. Inert gases like nitrogen or argon are used to displace oxygen in storage containers to prevent combustion or oxidation reactions. Storing them with oxidizing gases could lead to potential fire or explosion hazards.


What are inert gases?

Inert gases are the noble gases (He, Ne, Ar, Kr, Xe, and Rn). They used to be called the inert gases until Neil Bartlett proved that you could make compounds out of some of them, so they were renamed "inert" gases.

What is the inert gas that's lighter than air?

There are two problems with this question, one is that inert gas is more than one substance and the second is that so is air. Air is a mixture of nitrogen, oxygen, carbon dioxide, argon and other gases. The best way to determine its mass is to take an average between these components. Next, what's an inert gas? Strictly speaking, the inert gases are the noble gases, which are the elements in group 0 of the periodic table. They are helium, neon, krypton, radon, xenon and argon. Hang on..., isn't argon in air? Helium is the lightest inert gas and as anyone who has seen a helium balloon can testify, it is lighter than air. The further down group 0 you go, towards the likes of xenon and radon, the heavier they get. From krypton onwards, they are all heavier than air except.... ... except that all of the noble gases, or the inert gases, can be found in air, in very small amounts. So in a weird way, if you're asking if inert gases are heavier than air, you're asking if they're heavier than themselves. But to put it in the simplest terms, there is more than one inert gas. Helium can be considered an example of an inert gas that is lighter than air, whereas xenon can be considered an example of one that is heavier.


What is An inert gas with a greater atomic mass then helium?

Helium is the lightest noble gas, so neon, argon, krypton and xenon are all heavier noble gases. Radon's also a noble gas and it's heavier than helium, but it's radioactive so is it really inert?


Is neon a part of the noble gases family or the inert gases family?

Yes. Neon is a part of noble gases (or inert gases)


Why is pure gases another name for the Noble gases?

Pure gas is not another name- inert gas is - although this is has been superseded by noble gas as chmical compounds have been discovered for the heavier noble gases since 1963.
