Helium Neon Argon Krypton Xenon Radon
These are the nobel gasses which have their out electron shells full and thus don't bond easily with other atoms. Argon makes up almost 1% of the atmosphere.

∙ 15y agoAll elements can be in the form of a solid, a liquid or a gas. The 'state' of the element is determined by temperature and other factors. Elements that are gases at room temperature are all non-metals. Some elemental gases that are in a gaseous state at room temperature are as follows: Hydrogen Helium Nitrogen Neon Oxygen Fluorine Argon Ozone (O3) Chlorine Krypton Xenon http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch4/gases1.html#roomt

∙ 13y agoThis is not a simple question to answer, because several elements have this characteristic. In general, the Noble gases exhibit this behavior as they are inert. So:
He (Helium)
Ne (Neon)
Ar (Argon)
Kr (Krypton)
Xe (Xeon)
Rn (Radon)

What are visible particles in the air called?
Molecules. A common molecule in air is O2, or two oxygen atoms stuck together. A 'particle' is a general term for anything very, very small. A molecule specifically indicates a combination of two of more atoms. Atoms are the smallest things which can exist independently, they come in over 100 different types and all substances are made up of different combinations of atoms. For example iron is made up of Iron atoms but steel is made of iron atoms with some carbon atoms. Diamond is made of carbon atoms while petrol (gasoline) is made of a combination of carbon and hydrogen atoms. Water is a molecule made of oxygen and hydrogen. The air is a mixture of things. Nitrogen gas makes up most of the air, each molecule of nitrogen is made of two nitrogen atoms joined together. Oxygen is another major component of the air and again, each molecule is made of a pair of oxygen atoms. (Not all things are combined, helium is a gas found in the very highest parts of our atmosphere and is not a molecule but instead exists as individual atoms.)
Is water vapor is a liquid?
Because of the strong hydrogen bonds that exists in water it's non volatile.The hydrogen bond perform between hydrogen atoms and oxygen atoms.
What are the three types of particles atoms made of?
air
There are about as many atoms of air in your lungs at any moment as there are breaths of air in the atmosphere of?
the whole world
Does oxygen occur naturally in its pure form?
It depends on what you mean by the pure form of Oxygen. Air is about 20% Oxygen. It comes as a molecule of two atoms of oxygen tied together. The chemical formula is O₂ but a single oxygen would be O. A single oxygen molecule does not exist in nature.
Is a chlorine atom denser than air?
Density is how tightly packed the molecules or atoms are, so you can't find the density of a single atom. But a group of chlorine atoms are denser than air.
How is the universe noisey without air?
Sound waves cannot travel through space and be heard by humans. There is no air wich means the air cannot vibrate wich means our ears cannot pick it up.
How the atoms react in air pressure?
'atoms' cannot 'react' to air pressure for air pressure is generated from atoms (oxygen, noble gasses, water).
What are two ways that air exists?
air is in a balloon
What is the physical appearance of nitrogen?
You can't see it because it is a gas. Almost 80% of the air you beath is made of nitrogen. In the air nitrogen exists as N2, that is two nitrogen atoms bonded together to make a molecule.
Is air composed of atoms?
Yes. Atoms are everywhere.
How is sound energy is used?
sound is used through sound waves wich are all around us in the air.
Are oxygen and ozone chemically different from each other?
Slightly. "Oxygen" as it exists in the air, or if you buy a tank of it, is O2--two oxygen atoms bonded together. "Ozone" is O3--an unstable "allotrope" of oxygen.
Why does Atmospheric pressure exists because air has what?
Because air has water vapor.
Who invented air pressure?
Air pressure exists, it wasn't 'invented' it was discovered.
What is between the atoms of a solid?
air
An air temperature of 95DC most often exists in which layer of the atmosphere?
The air temperature of 95 degrees Celsius most often exists in the thermosphere layer of the atmosphere.
