Like Wave, Like Particle, Not Attracted to Electrons II

From the previous post "Like Wave, Like Particle, Not Attracted to Electrons", the energy in required in moving from r at to reo is

PEe=mec2limr{ln(rreo)+C(reor)}

Energy required in moving from to ref is

PEe=mec2limr{ln(rref)+C(refr)}

So, the energy required in moving the electron from from reo to ref is

Es=PEe(ref)PEe(reo)

Es=mec2limr{ln(rref)ln(rreo)+C(refr)C(reor)}

Es=mec2{ln(reoref)+C(refreo)}

which is the same expression as Es as before.

From previous calculation of atomic radius we find that, the centripetal force is of the form,

mec2reo=q24πεor2eo.(4383).32232

and

mec2reo=q24πεor2eo(333)

In general,

mec2reo=q24πεor2eo.A

where A is a numerical constant dependent on the configuration of the electrons around the positive charge.  Using this expression to bring a charge from infinity to its final configuration position along the line joining it and the positive center.

PE=Areorq24πεor2dr

PE=q2A4πεo{1r}|reor

PE=q2A4πεo1reo

The negative sign indicates that this potential is lower than that at which is zero.  Numerically, the energy stored when the electron is pushed to a lower orbit, (photon and electron repel) is equal to this PE when the electron is ejected (ie the atom is ionized) after the photon has passed.

Es=mec2{ln(reoref)+C(refreo)}=q2A4πεo1reo

ln(reorefeC(refreo))=q2A4πεomec21reo

reorefeC(refreo)=eq2A4πεomec21reo

refeC.ref=reoeC.reoeq2A4πεomec21reo

because of the eq2A4πεomec21reo<1    factor,  and xeCx is monotonous increasing for x<1 for all values of C.    ref<reo for r<1.  Which is an acceptable result.

Given an element the constant A is determined from distribution of electrons around the positive center.  The factor C....
