  2. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    The p-orbitals oriented in the z-direction (p z) can overlap end-on forming a bonding (symmetrical) σ orbital and an antibonding σ* molecular orbital. In contrast to the sigma 1s MO's, the σ 2p has some non-bonding electron density at either side of the nuclei and the σ* 2p has some electron density between the nuclei.

  3. Fluorine - Wikipedia

    en.wikipedia.org/wiki/Fluorine

    Fluorocarbon gases are generally greenhouse gases with global-warming potentials (GWPs) of about 100 to 10,000; sulfur hexafluoride has a value of around 20,000. [288] An outlier is HFO-1234yf which is a new type of refrigerant called a Hydrofluoroolefin (HFO) and has attracted global demand due to its GWP of less than 1 compared to 1,430 for ...

  4. Molecular orbital - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital

    A molecular orbital can specify the electron configuration of a molecule: the spatial distribution and energy of one (or one pair of) electron(s). Most commonly a MO is represented as a linear combination of atomic orbitals (the LCAO-MO method), especially in qualitative or very approximate usage.

  5. Difluorocarbene - Wikipedia

    en.wikipedia.org/wiki/Difluorocarbene

    The molecular orbitals are built from an empty p-orbital on the central carbon atom and two orbitals on the fluorine atoms. Four electrons, the carbon orbital is empty, the fluorine orbitals both carry two electrons, need to find a place, thus filling the lower two of the MO-set.

  6. Fluorine compounds - Wikipedia

    en.wikipedia.org/wiki/Fluorine_compounds

    The noble metals ruthenium, rhodium, palladium, platinum, and gold react least readily, requiring pure fluorine gas at 300–450 °C (575–850 °F). [14] Fluorine reacts explosively with hydrogen in a manner similar to that of alkali metals. [15] The halogens react readily with fluorine gas [16] as does the heavy noble gas radon. [17]

  7. Electron configuration - Wikipedia

    en.wikipedia.org/wiki/Electron_configuration

    Noble gas configuration is the electron configuration of noble gases. The basis of all chemical reactions is the tendency of chemical elements to acquire stability . Main-group atoms generally obey the octet rule , while transition metals generally obey the 18-electron rule .

  8. Molecular orbital theory - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_theory

    In chemistry, molecular orbital theory (MO theory or MOT) is a method for describing the electronic structure of molecules using quantum mechanics. It was proposed early in the 20th century. The MOT explains the paramagnetic nature of O 2, which valence bond theory cannot explain.
