Germanium has 32 electrons per atom. 4 of those are valence electrons. Thus, germanium has 28 core electrons. Germanium has 32 electrons per atom. 4 of those are valence electrons.
Silicon sits next to aluminum and below carbon in the periodic table. Carbon, silicon and germanium (germanium, like silicon, is also a semiconductor) have a unique property in their electron structure -- each has four electrons in its outer orbital. This allows them to form nice crystals. The four electrons form perfect covalent bonds with four neighboring atoms, creating a lattice.
