WebPeriodic Trends. In the SparkNote on the Periodic table we discussed a number of simple periodic trends. In this section we will discuss a number of more complex trends, the understanding of which relies on knowledge of atomic structure. Before getting into these trends, we should engage a quick review and establish some terminology. WebFermi level (E F) and vacuum level (E VAC) positions, work function (WF), energy gap (E G), ionization energy (IE), and electron affinity (EA) are parameters of great importance for any electronic material, be it a metal, …
