  2. Metallic bonding - Wikipedia

    en.wikipedia.org/wiki/Metallic_bonding

    Metallic bonding is mostly non-polar, because even in alloys there is little difference among the electronegativities of the atoms participating in the bonding interaction (and, in pure elemental metals, none at all). Thus, metallic bonding is an extremely delocalized communal form of covalent bonding.

  3. Delocalized electron - Wikipedia

    en.wikipedia.org/wiki/Delocalized_electron

    Metallic structure consists of aligned positive ions in a "sea" of delocalized electrons. This means that the electrons are free to move throughout the structure, and gives rise to properties such as conductivity. In diamond all four outer electrons of each carbon atom are 'localized' between the atoms in covalent bonding. The movement of ...

  4. Metal–metal bond - Wikipedia

    en.wikipedia.org/wiki/Metal–metal_bond

    They can also vary according to bond order. The topic of metal–metal bonding is usually discussed within the framework of coordination chemistry, [1] but the topic is related to extended metallic bonding, which describes interactions between metals in extended solids such as bulk metals and metal subhalides. [2]

  5. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

  6. Coordinate covalent bond - Wikipedia

    en.wikipedia.org/wiki/Coordinate_covalent_bond

    Coordinate covalent bonding is ubiquitous. [6] In all metal aquo-complexes [M(H 2 O) n] m +, the bonding between water and the metal cation is described as a coordinate covalent bond. Metal-ligand interactions in most organometallic compounds and most coordination compounds are described similarly.

  7. Electron pair - Wikipedia

    en.wikipedia.org/wiki/Electron_pair

    MO diagrams depicting covalent (left) and polar covalent (right) bonding in a diatomic molecule. In both cases a bond is created by the formation of an electron pair. Because electrons are fermions, the Pauli exclusion principle forbids these particles from having all the same quantum numbers.

    Firefighters responded to an average of 155 home fires ignited by Christmas trees each year from 2018 to 2022, as well as an additional 835 residential structure fires sparked by decorations other ...

  9. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    A less often mentioned type of bonding is metallic bonding. In this type of bonding, each atom in a metal donates one or more electrons to a "sea" of electrons that reside between many metal atoms. In this sea, each electron is free (by virtue of its wave nature) to be associated with a great many atoms at once. The bond results because the ...
