  2. Orbital hybridisation - Wikipedia

    en.wikipedia.org/wiki/Orbital_hybridisation

    In chemistry, orbital hybridisation (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.

  3. Isovalent hybridization - Wikipedia

    en.wikipedia.org/wiki/Isovalent_hybridization

    In chemistry, isovalent or second order hybridization is an extension of orbital hybridization, the mixing of atomic orbitals into hybrid orbitals which can form chemical bonds, to include fractional numbers of atomic orbitals of each type (s, p, d). It allows for a quantitative depiction of bond formation when the molecular geometry deviates ...

  4. Hybridisation - Wikipedia

    en.wikipedia.org/wiki/Hybridisation

    Hybridization (or hybridisation) may refer to: Hybridization (biology) , the process of combining different varieties of organisms to create a hybrid Orbital hybridization , in chemistry, the mixing of atomic orbitals into new hybrid orbitals

  5. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    This is a weighted sum of the wavefunctions. Now choose a second hybrid orbital s + √ λ j p j, where p j is directed in some way and λ j is the amount of p character in this second orbital. The value of λ j and direction of p j must be determined so that the resulting orbital can be normalized and so that it is orthogonal to the first ...

  6. Orbital overlap - Wikipedia

    en.wikipedia.org/wiki/Orbital_overlap

    In chemical bonds, an orbital overlap is the concentration of orbitals on adjacent atoms in the same regions of space. Orbital overlap can lead to bond formation. Linus Pauling explained the importance of orbital overlap in the molecular bond angles observed through experimentation; it is the basis for orbital hybridization.

  7. Nucleic acid hybridization - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_hybridization

    Fluorescence in situ hybridization (FISH) is a laboratory method used to detect and locate a DNA sequence, often on a particular chromosome. [4]In the 1960s, researchers Joseph Gall and Mary Lou Pardue found that molecular hybridization could be used to identify the position of DNA sequences in situ (i.e., in their natural positions within a chromosome).

  8. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    The concepts of orbital hybridization and resonance augment this basic notion of the electron pair bond. In molecular orbital theory, bonding is viewed as being delocalized and apportioned in orbitals that extend throughout the molecule and are adapted to its symmetry properties, typically by considering linear combinations of atomic orbitals ...

  9. Homolysis (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Homolysis_(chemistry)

    Orbital hybridization. The s-character of an orbital relates to how close electrons are to the nucleus. In the case of a radical, s-character more specifically relates to how close the single electron is to the nucleus. Radicals decrease in stability as they are closer to the nucleus, because the electron affinity of the orbital increases.
