... atom has the same number of electrons as there are protons, so, on the
whole, it is electrically neutral. The electrons have discrete kinetic energy
levels, which increase with the orbital radius. When atoms bond together to form
a solid, the electron energy levels merge into bands. In electrical conductors,
these bands are continuous but in insulators and semiconductors there is an
"energy gap", in which no electron orbits can exist, between the inner valence

the atoms in a solid by orbiting 2 adjacent nucleii, while conduction electrons,
being less clos ... |
