No - there are many gases that contain more than one or two atoms. Some examples are:
Carbon Dioxide: 3 atoms
Acetylene: 4 atoms
Methane: 5 atoms
Ethylene: 6 atoms
.
.
.
and the list goes on. It is true though that as the more atoms a molecule consists of, the less likely it is to be a gas at a temperature we are familiar with. Pretty nearly all molecules can be gases if the pressure is low enough and the temperature is high enough (unless they decompose before they can be heated enough to make their vapor pressure exceed the ambient pressure).
What else can I help you with?
Are noble gases diatomic?
Noble gases have full outer electron shells, thus have no 'desire' to combine with anything, even its "brothers."Noble Gases are not diatomic.
Why don't noble gases form diatomic molecules?
Noble gases have a stable electron configuration with a full outer energy level, so they do not need to form bonds to achieve stability. As a result, they exist as monatomic gases and do not naturally form diatomic molecules.
What are the only elements in that exist you nature as isolated atoms?
Helium, neon, and argon are the only elements that exist in nature as isolated atoms, due to their stable electronic configurations that do not readily form chemical bonds with other elements. These elements are known as noble gases for their inert nature.
Is not an example of a diatomic element?
A diatomic element exists as a molecule containing two of its atoms, such as chlorine (Cl2) and bromine (Br2). Elements that are not diatomic include monatomic elements (noble gases such as Ar, Ne) and triatomic elements (ozone, O3).
Which is not a diatomic gas?
chlorine, the other three are examples of noble gases
Are noble gases diatomic?
Noble gases have full outer electron shells, thus have no 'desire' to combine with anything, even its "brothers."Noble Gases are not diatomic.
Do noble gases occur in diatomic form?
No. Noble gases have completely filled valence orbitals, have stable electronic configuration. Hence they exist as monoatomic species.
Why don't noble gases form diatomic molecules?
Noble gases have a stable electron configuration with a full outer energy level, so they do not need to form bonds to achieve stability. As a result, they exist as monatomic gases and do not naturally form diatomic molecules.
Which element does NOT exist as a diatomic gas at room temperature and atmospheric pressure?
All group 18 elements (the noble gases) exist as monatormic gases at room temperature and standard pressure. All other elements form diatomic gases, if they exist as gas under the specified conditions. Among the listed elements there is only one noble gas: Argon
What are the only elements in that exist you nature as isolated atoms?
Helium, neon, and argon are the only elements that exist in nature as isolated atoms, due to their stable electronic configurations that do not readily form chemical bonds with other elements. These elements are known as noble gases for their inert nature.

chlorine, the other three are examples of noble gases
All the elemental gases except for the Noble Gases come in what kind of special molecules?
All the elemental gases except for the noble gases come in molecules that are unstable. The noble gases are all stable, they have the maximum number of valence electrons that their outer shell can hold.
How do psychical and chemical properties of halogens compare with those of the inert gas?
At room temperature the lighter halogens, F, Cl are diatomic gases, Br is a liquid, I is a solid. All of the halogens are colored and toxic. The noble gases are all colorless odorless non chemically toxic monoatomic gases. (Radon is radioactive).
How do the physical and chemical properties of the halogens compare with those of the noble glasses?
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
How do halogens differ from noble gases?
halogens are much more reactive
Which noble gas only has one atom?
All noble gases have only one type of atom
