WebAug 31, 2024 · Determine the electron configuration of silicon. Solution . Silicon is element No. 14. It has 14 protons and 14 electrons. The lowest energy level of an atom is filled first. The arrows in the graphic show the s quantum numbers, spin up and spin down. Step A shows the first two electrons filling the 1s orbital and leaving 12 electrons. WebEnergy Bands Consider an isolated silicon atom; its energy levels are quantized (see the Bohr model for Hydrogen). When two identical atoms are brought closer together, the quantized energy levels hybridize and split into two different levels because of the mutual interaction of the two atoms.
