Another region of applicability is for a polyatomic gas which dissociates completely before it starts to ionize.
It might be instructive as an illustration to consider the uniform flow of a polyatomic gas past a blunt-nosed body over a wide range of speeds.
For example, the excitation of rotational and vibrational modes of a polyatomic gas (without dissociation) can be represented by the equation of state of a thermally perfect gas.
An example of a polyatomic ion is the hydroxide ion - consisting of one oxygen atom and one hydrogen atom, hydroxide has a charge of 1.
The hydronium cation, also known as hydroxonium is the positively charged polyatomic ion with the chemical formula.
However, in quantum physics, organic chemistry, and biochemistry, the term "molecule" is often used less strictly, also being applied to polyatomic ions.
Supplying the reactive/collisional gas into the tip of the skimmer cone induces extra collisions and reactions that destroy polyatomic ions in the passing plasma.
Among the polyatomic nonmetals, carbon, phosphorus and seleniumwhich border the metalloidsbegin to show some metallic character.
