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.
This statement is not accurate. There are typically billions of atoms in a single breath of air and trillions of breaths in the Earth's atmosphere, making the comparison between the two vastly different. The number of atoms in your lungs is very small compared to the total number of breaths in the atmosphere.
A bolt of lightning primarily exists in the plasma phase. This is a high-energy state where electrons are separated from atoms, creating a conducting medium that allows electricity to flow through the air.
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.)
Everywhere around you. The crust of the earth and all things on it are pretty much atoms of one kind or another. Matter as we know it is generally made up of atoms. Atoms are the building blocks of molecules. We are atoms. Certainly there aren't atoms as we know them in stars because they are too hot. Matter there there exists as plasma. And in space where gas and charged particles swirl and eddy, atoms are not the norm. But 'round these parts, we can't help but find them.
When a piece of copper is heated in the presence of air, it can react with oxygen to form copper oxide. This can result in an increase in weight due to the addition of oxygen atoms from the air to the copper atoms.
Oxygen is an element. Gaseous oxygen (the kind in the air you breathe) is called molecular as it consists of two oxygen atoms (O2).
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.
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.

There are typically billions of atoms in a single breath of air and trillions of breaths in the Earth's atmosphere, making the comparison between the two vastly different.

Elemental nitrogen in the air occurs in diatomic molecules and therefore has the formula N2.
'atoms' cannot 'react' to air pressure for air pressure is generated from atoms (oxygen, noble gasses, water).
sound is used through sound waves wich are all around us in the air.
Yes. Atoms are everywhere.
Atmospheric pressure exists because air has weight. The weight of the air above exerts a force on the air below it, resulting in pressure at the Earth's surface.
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.
Water is a single chemical compound in its liquid form (H20). Air is a mixture of many elements and compounds in gaseous form and can include the gaseous form of water as one of its components.
Water exists on land as a liquid or solid (ice) and in the air as a gas (water vapor).
