From the previous post "Hot Topic, Less Mumble, Jumble...",
T=12(qv2rc+mv2rg)
then for an electron, its temperature is given by,
Te=12(qv2rc+mev2rge)
and for a proton,
Tp=12(qv2rc+mpv2rgp)
and for a neutron,
Tn=12mnv2rgn
Temperature associated with an atom is,
Tatom=n(Te+Tp)+(N−n)Tn
where N is the mass number and n the atomic number,
Tatom=nTe+nTp+(N−n)Tn
Let,
Tnucleus=nTp+(N−n)Tn
Tatom=nTe+Tnucleus
And since,
Te<nTe<nTp<nTp+(N−n)Tn
Te<Tnucleus
For the sake of completeness.
