More Photon Mass, More Power!

Below is a table of elements with known Work Function $\Phi$ and Atomic radii ${r}_{e}$. Values of  photon mass ${m}_{p}$ are calculated and averaged, using

${m}_{p}= \cfrac{1}{c^2}.(\cfrac{h.c}{4{r}_{e}}+\Phi)$,

where Planck's Constant   $h$ = 4.135667516e-15 eV, light speed   $c$ = 299792458 m s^-1
