The smallest and least dense gaseous element is Hydrogen. Hydrogen is made up of only one proton and one electron. This makes it the smallest molecule in the world! Because it is so small it can travel through other gasses with ease.
an element is chemically active till it does not attain an inert gas configuration.
Neon and argon are two other gases that are denser than helium and do not react easily with other elements.
gas
Argon gas is an element. It will be element only. It can be part of some mixture. But never ever be a part of the compound. It is a noble gas.
Hydrogen gas is an element because it is composed only of hydrogen atoms.
Flourine
a couler less gas that burns easily and is the lightest element of the universe
flows easily, so gas bubbles move up through it and escape fairly gently.

I suppose methane gas flows most easily. If the question meant a liquid, then I guess it would be oil.
metals have electrons in the valence band that easily separate, forming an "electron gas" that fills the metal. This "gas" readily flows in response to an electric field placed across the metal.
Mercury vapor is the element mercury in the gas phase. It must be a pretty high temperature or low pressure because mercury doesn't turn into a gas very easily!
When you fill it up gas flows to the reserve tank first and then flows into the main tank.
Neon and argon are two other gases that are denser than helium and do not react easily with other elements.
Easily. Xenon is an inert or "noble" gas which does not participate in any biological or chemical reactions; it exists in the atmosphere as a "trace" element.
It is changing he element that is a liquid from a liquid to water vapor. A gas.
