The Formation Of Standing Waves

Standing waves occur when the frequency of the wavelength matches the dimensions of the container. An understanding of standing waves helps explain why electrons are restricted to different orbits. Duration: 7:35

Energy Level Diagrams

There are many atomic orbitals that describe the regions of space where electrons are found. Energy-level diagrams are used to describe these orbitals and how they are occupied by electrons. Duration: 7:03

Electron Configurations

An electron configuration describes the arrangement of electrons in the orbitals of an atom and also gives rise to its properties. Elements with similar chemical and physical properties are found grouped together in the same vertical column of the periodic table. Duration: 4:15.
