In a crystal of a metal, all the atoms are
bonded and some electrons shared. You
You can think of some of the electrons as
running in each direction along the chain.
When an electric field is put on the chain, is
shifts the balance and more electrons go one
way than the other.

Unless we are going to be materials science
physicists, we don’t really need to understand the
quantum view of conduction.
Instead, we construct a bunch analogies
that have some of the correct features.
