Electron diffraction is most frequently used in solid state physics and chemistry to study the crystal structure of solids. Experiments are usually performed in a transmission electron microscope (TEM), or a scanning electron microscope (SEM) as electron backscatter diffraction.his phenomenon is commonly known as waveâparticle duality, which states that a particle of matter (in this case the incident electron) can be described as a wave. For this reason, an electron can be regarded as a wave much like sound or water waves.
This is a Lewis dot structure of carbon dioxide. Todd Helmenstine. Electron Domain Definition: Electron domain refers to the number of lone pairs or bond locations around a particular atom in a molecule. Bond location is independent of whether the bond is a single, double or triple bond. Electron domain is used in VSEPR theory to determine the molecular geometry of a molecule. Examples: CO 2 (see picture) has 2 electron domains around the central carbon atom.
