Gases that are made up of only two atoms that can be both of the same or of different elements.
Hydrogen, oxygen, nitrogen, bromine, chlorine, iodine, and fluorine are seven common gases that exist as diatomic molecules of the same element. However there are still examples of diatomic molecules that are made up of non- identical atoms such as carbon monoxide, hydrogen chloride and nitric oxide.

Diatomic gases are molecules made up of two atoms of the same element bonded together. Examples include hydrogen (H2), oxygen (O2), and nitrogen (N2). These gases are commonly found in nature and have specific properties due to their molecular structure.
substances made of molecules bonded with the same identical molecules repeatedly
Noble gases have full outer electron shells, thus have no 'desire' to combine with anything, even its "brothers."Noble Gases are not diatomic.
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.
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).
Air is primarily composed of nitrogen (N2) and oxygen (O2) molecules. Both nitrogen and oxygen are diatomic molecules, meaning they naturally exist in pairs (N2 and O2) due to their electron configuration and bonding tendencies. This is why air is considered diatomic.
Diatomic gas has a higher specific heat compared to monoatomic gas due to the additional degrees of freedom associated with the rotational motion of diatomic molecules. This allows diatomic gases to store more energy as heat per unit mass without a large temperature increase.
