To find the atomicity of an ideal gas you can use γ = Cp/Cv.
Ammonia is a tetra atomic gas.
The gas is diatomic.
Neon is an inert gas (noble gas), natural, atomic number 10; it is a monoatomic ags and its atomicity is 1. neon is used as filling gas in red lamps, in lasers, in plasma displays, in cryogenic applications, etc.
Atomicity of a gas is the number of an element present in one molecule of that element.The gases can be:-monoatomic .E.g-Helium(He),diatomic,E.g-Hydrogen(H2),triatomic,E.g-Ozone(O3),polyatomic,E.g-Sulphur(S8).
Atomicity of carbon is 2
the atomicity of gold is 79
Atomicity of boron is 1*
its atomicity is 2.....................
atomicity of oxygen is 2atoms
The atomicity of the ion (HCO3)- is five.
the atomicity of ozone is 3 hehehehe./////////////......................
the Atomicity of sodium is 1. and hence it is called a monoatomic molecule.
