Is helium the lightest inert gas?
Yes, it is.
Why helium gas is used in weather balloons but not hydrogen?
Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
What is the density of INERT gas?
That depends on what inert gas you're taling about.
Is helium the lightest gas in the atmosphere?
helium is the lightest air
Is CO inert?
Carbon monoxide is not an inert gas.
Is helium the lightest inert gas?
Yes, it is.
Which is the lightest inert gas which makes your voice squeaky?
Helium
What is the lightest inert?
Helium is the lightest inert gas. It is a monatomic gas with an average atomic weight of about 4. The only atom lighter than that is hydrogen - which forms a diatomic gas with molecular wight of about 2 - BUT - it is anything but inert! Hydrogen is highly flammable and a commonly used reactant for a lot of syntheses. The next lightest gas that is sort of inert is nitrogen - which is quite a bit heavier - at a molecular weight of about 14. (Nitrogen is not particularly reactive at room temperature so it is often used as an "inert" gas - even though it isn't really totally inert.) The next lightest noble gas is Neon - which, although it forms a monatomic gas, has an atomic wight of about 20 - even heavier than Nitrogen.
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?
Was helium the lightest gas?
Hydrogen was, and is, the lightest gas
What happens if you replace inert gas in glass bulb of electric lamb by nitrogen gas?
inert gas inert gas inert gas
Is argon an inert gas?
argon is an inert gas
Is hydrogen gas the lightest gas in the world?
Yes it is, and it's also the lightest gas in the universe.
Why helium gas is used in weather balloons but not hydrogen?
Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
What is inert argon gas?
All argon gas is inert.
Which matter is lightest in weight?
gas is the lightest in weight
What is the density of INERT gas?
That depends on what inert gas you're taling about.
