Noble gases have full outer electron shells, thus have no 'desire' to combine with anything, even its "brothers."

Which is not a diatomic gas?
chlorine, the other three are examples of noble gases
Why don't noble gases form diatomic molecules?
Noble gas atoms can not lose energy by combining to form diatomic molecules, because each individual atom already has a filled outer electron shell.
What are the only elements in that exist you nature as isolated atoms?
I would say the noble gases since as gases their atoms are isolated and they do not form diatomic molecules like all the other gaseous elements.
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).
What is true about atoms in helium gas?
They are helium atoms and have all the properties of helium. Helium is mono-atomic [as are all of the noble gases] Non-noble gases [those gases that react with other elements/compounds] are diatomic meaning that in the gaseous state the atoms are paired on to another.
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.

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

Why air is diatomic?
Air is diatomic because it is a mixture of inert gases like nitrogen which is also diatomic.
The elements that do not ordinarily form compounds are?
Noble gases do not normally form compounds.
What happens when two noble gases are combined?
Noble gases do not react chemically with other noble gases.
What are the noble gases in Column 18 called?
inert gases / noble gases
