  2. Charge carrier density - Wikipedia

    en.wikipedia.org/wiki/Charge_carrier_density

    The carrier density is important for semiconductors, where it is an important quantity for the process of chemical doping.Using band theory, the electron density, is number of electrons per unit volume in the conduction band.

  4. Davisson–Germer experiment - Wikipedia

    en.wikipedia.org/wiki/Davisson–Germer_experiment

    To measure the number of electrons that were scattered at different angles, a faraday cup electron detector that could be moved on an arc path about the crystal was used. The detector was designed to accept only elastically scattered electrons. During the experiment, air accidentally entered the chamber, producing an oxide film on the nickel ...

  5. Total electron content - Wikipedia

    en.wikipedia.org/wiki/Total_electron_content

    TEC plot for the continental USA, made on 2013-11-24. Total electron content (TEC) is an important descriptive quantity for the ionosphere of the Earth. TEC is the total number of electrons integrated between two points, along a tube of one meter squared cross section, i.e., the electron columnar number density.

  6. Electronegativity - Wikipedia

    en.wikipedia.org/wiki/Electronegativity

    The electronegativity of an atom changes depending on the hybridization of the orbital employed in bonding. Electrons in s orbitals are held more tightly than electrons in p orbitals. Hence, a bond to an atom that employs an sp x hybrid orbital for bonding will be more heavily polarized to that atom when the hybrid orbital has more s character.

  7. d electron count - Wikipedia

    en.wikipedia.org/wiki/D_electron_count

    The d electron count or number of d electrons is a chemistry formalism used to describe the electron configuration of the valence electrons of a transition metal center in a coordination complex. [1] [2] The d electron count is an effective way to understand the geometry and reactivity of transition metal complexes.

  8. Polyhedral skeletal electron pair theory - Wikipedia

    en.wikipedia.org/wiki/Polyhedral_skeletal...

    When counting electrons for each cluster, the number of valence electrons is enumerated. For each transition metal present, 10 electrons are subtracted from the total electron count. For example, in Rh 6 (CO) 16 the total number of electrons would be 6 × 9 + 16 × 2 − 6 × 10 = 86 – 60 = 26.

  9. Electron density - Wikipedia

    en.wikipedia.org/wiki/Electron_density

    Electron density or electronic density is the measure of the probability of an electron being present at an infinitesimal element of space surrounding any given point. It is a scalar quantity depending upon three spatial variables and is typically denoted as either () or ().
