Diatomic gas:

Diatomic molecules—so named because they only contain two atoms of the same or different chemical elements—are molecules that are made up of two atoms. A diatomic molecule is considered to be homonuclear if it contains two atoms of the same element, such as oxygen ($O2$) or hydrogen ($H2$). In contrast, a molecule is considered to be heteronuclear if it consists of two distinct atoms in a diatomic compound, such as carbon monoxide ($CO$) or nitric oxide ($NO$). A homonuclear diatomic molecule has a non-polar link.

Only the gases hydrogen ($H2$), nitrogen ($N2$), oxygen ($O2$), fluorine ($F2$), and chlorine ($Cl$) may form stable homonuclear diatomic molecules at standard temperature and pressure ($STP$).

The noble gases at $STP$ are likewise gases, however they are monatomic (helium, neon, argon, krypton, xenon, and radon). To differentiate them from other gases that are chemical compounds, the homonuclear diatomic gases and noble gases are collectively referred to as "elemental gases" or "molecular gases."

The halogens bromine ($Br2$) and iodine ($I2$) also produce diatomic gases at somewhat higher temperatures.

 With the exception of astatine and tennessine, whose existence is questionable, all halogens have been detected as diatomic molecules.

When other elements are vaporized, they produce diatomic molecules, but when they are cooled, these diatomic species polymerize again. Diphosphorus is produced by heating (cracking) elemental phosphorus ($P2$). Most sulphur vapour is disulfur ($S2$). In the gas phase, it is known that dilithium ($Li2$) and disodium ($Na2$) exist. Sextuple bonds are used to create ditungsten ($W2$) and dimolybdenum ($Mo2$) in the gas phase. Diatomic in nature is dirubidium ($Rb2$).

Number of atoms present in $0.1$mole of a diatomic gas is $1.806 * 10^{23}$ atoms.
