These gases are called noble because they are very unreactive. Also: - helium: from the Greek word helios with the meaning sun - neon: idem with the mening of new - argon: idem, with the meaning of inactive - krypton: idem with the meaning of hidden - xenon: idem, with the meaning of strange - radon: the name is derived from radium emanation
Is Clay imperable or perable?
Clay is permeable, meaning it allows liquids or gases to pass through it. It is not impermeable, which would prevent the passage of liquids or gases.
Are helium argon and neon inactive gases?
Yes, helium, argon, and neon are considered inactive gases because they are chemically inert, meaning they do not readily react with other elements to form compounds. They are also known as noble gases.
What are the Earth's sphere's?

What is the literal meaning of atmosphere?
The word "atmosphere" comes from the Greek words "atmos" meaning vapor and "sphaira" meaning sphere, referring to the layer of gases surrounding a planet. It is the enveloping layer of gases surrounding the Earth or another planet, providing the air that we breathe and playing a crucial role in regulating climate and weather.
Noble gases usually exist as what?
Noble gases usually exist as monatomic (single atom) gases because they have a stable electron configuration and are inert, meaning they do not easily react with other elements. This makes them chemically unreactive and often found in their elemental form in nature.
Can gases expand?
No, they diffuse until an equilibrium is established meaning there is an equal spread of the gasses molecules. - Tony
Why do gasses have neigthter a fixed volumn?
Because gases are compressible, meaning their volume depends on the pressure exerted on them.
Why is the layer of air that surrounds the Earth the atmosphere?
It originates from Greek atmos meaning 'vapour' and sphaira meaning 'ball or globe'. The Earth's atmosphere is a thin layer of gases that surrounds the Earth. It composed of 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide, and trace amounts of other gases. Because that is what the layer of gases that surround an astronomical body are called.
What is meaning of scavenging?
Act or process of expelling the exhaust gases from the cylinder by some special means, as, in many four-cycle engines, by utilizing the momentum of the exhaust gases in a long exhaust pipe.
What is argon name after?
It comes from the greek word meaning "inactive" as, like all noble gases, it is largely inert.
