metallic bond size of,
\(a_{\psi}=126\,pm\)
from which
\(f_{osc}=c\sqrt{\cfrac{2\pi}{(126*10^{-12})}}=6.6946e13\,Hz\)
If we were to deliver energy by the impact of electrons,
\(I_{osc}=q_e*f_{osc}=1.602176565\text{e-19}*6.6946e13=1.07259\text{e-5}\,A\approx10.7\,\mu A\)
What will happen? What is the nature of \(f_{osc}\) resonance?
And for aluminium \(Al\),
\(f_{osc}=c\sqrt{\cfrac{2\pi}{(143*10^{-12})}}=6.2841e13\,Hz\)
\(I_{osc}=q_e*f_{osc}=1.602176565\text{e-19}*6.2841e13=1.007\text{e-5}\,A\approx10.1\,\mu A\)
Does the metal turn transparent when \(I_{osc}\) passes through it? It is difficult to image the metal turning red hot at such low current level. With a hole in the middle of each constituent atom, the metal may just be hollow.
Good night...
