The instrument is likely a tool to help determine the electronic configuration of atoms. The following aspects are covered: * Orbital filling diagram * Electron configuration * Noble gas electron configuration (or shorthand) * Distinguishing among rules * Two mathematical formulas * Finding the number of unpaired electrons * Exceptions * Location of s, p, d, and f blocks on the periodic table.
