@MartianCactus, Since, you are a 10 grader (damn, I missed that), what I wanted to mean could be put in Feynman's words:

> [...] how an electron can ride right through the crystal and flow perfectly freely even though it has to hit all the atoms. It does so by having its amplitudes going pip-pip-pip from one atom to the next, working its way through the crystal. That is how a solid can conduct electricity.

@orthocresol It's that the $n$th base state of the electron implies the electron is at atom number $n$ at $x_n\;.$ You can make the basis as $|n-1\rangle, ~|n\rangle, ~|n+1\rangle\;.$

@MAFIA36790 Typo: $\mathrm C_n = a_ne^\frac{-\mathrm iEt}{\hbar}\;.$

@orthocresol I was talking about conduction/propagation of electron through solid/crystal. I know I may have not written rigorously in haste..... sorry ;P

stares at @ortho

@MartianCactus You can edit your message.

@orthocresol o/

I would also go back to my studies; bye @ortho.

@orthocresol where?

@orthocresol ;))

@orthocresol Enjoy then ;D
