Estimating number of electrons available for conduction
i don't want to use proper fermi dirac or anything i want an easy way to estimate. ive been asked to estimate the number of electrons in a metal, and the number of electrons available for conduction.
so for number of electrons in a metal is easy
# of e= density of electrons / volume
i know how to find density of states and all that, but thats working out the answer not really "estimating".
how could i estimate # of e available for conduction
