  2. Diphosphorus - Wikipedia

    en.wikipedia.org/wiki/Diphosphorus

    Diphosphorus is an inorganic chemical with the chemical formula P. 2. Unlike nitrogen, its lighter pnictogen neighbor which forms a stable N 2 molecule with a nitrogen to nitrogen triple bond, phosphorus prefers a tetrahedral form P 4 because P-P pi-bonds are high in energy. Diphosphorus is, therefore, very reactive with a bond-dissociation ...

  3. Bond order - Wikipedia

    en.wikipedia.org/wiki/Bond_order

    Bond order. In chemistry, bond order is a formal measure of the multiplicity of a covalent bond between two atoms. As introduced by Linus Pauling, bond order is defined as the difference between the numbers of electron pairs in bonding and antibonding molecular orbitals. Bond order gives a rough indication of the stability of a bond.

  4. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    The σ from the 2p is more non-bonding due to mixing, and same with the 2s σ. This also causes a large jump in energy in the 2p σ* orbital. The bond order of diatomic nitrogen is three, and it is a diamagnetic molecule. [12] The bond order for dinitrogen (1σ g 2 1σ u 2 2σ g 2 2σ u 2 1π u 4 3σ g 2) is three because two electrons are now ...

  5. Molecular orbital theory - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_theory

    Bond order is the number of chemical bonds between a pair of atoms. The bond order of a molecule can be calculated by subtracting the number of electrons in anti-bonding orbitals from the number of bonding orbitals, and the resulting number is then divided by two. A molecule is expected to be stable if it has bond order larger than zero.

  6. Phosphorus - Wikipedia

    en.wikipedia.org/wiki/Phosphorus

    Phosphorus. Phosphorus is a chemical element; it has symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare ...

  7. Phosphorus monoxide - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_monoxide

    The bond order is about 1.8. [5] The P=O bond in PO has a dissociation energy of 6.4 eV. [16] The bond length of the PO double bond is 1.476 Å, and free PO shows an infrared vibrational frequency of 1220 cm −1 due to the stretching of the bond. [17]

  8. Allotropes of phosphorus - Wikipedia

    en.wikipedia.org/wiki/Allotropes_of_phosphorus

    White phosphorus (left), red phosphorus (center left and center right), and violet phosphorus (right) White phosphorus and resulting allotropes. Elemental phosphorus can exist in several allotropes, the most common of which are white and red solids. Solid violet and black allotropes are also known. Gaseous phosphorus exists as diphosphorus and ...

  9. Orbital hybridisation - Wikipedia

    en.wikipedia.org/wiki/Orbital_hybridisation

    Checked. 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. For example, in a carbon atom which forms four ...
