  3. Nitrogen - Wikipedia

    en.wikipedia.org/wiki/Nitrogen

    Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk-delivered ...

  4. Dissociation (chemistry) - Wikipedia

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

    Dissociation in chemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner.

  5. Molecule - Wikipedia

    en.wikipedia.org/wiki/Molecule

    Circa 450 BC Empedocles imagined fundamental elements (fire (), earth (), air (), and water ()) and "forces" of attraction and repulsion allowing the elements to interact. A fifth element, the incorruptible quintessence aether , was considered to be the fundamental building block of the heavenly bodies.

  6. Bond length - Wikipedia

    en.wikipedia.org/wiki/Bond_length

    A table with experimental single bonds for carbon to other elements is given below. Bond lengths are given in picometers.By approximation the bond distance between two different atoms is the sum of the individual covalent radii (these are given in the chemical element articles for each element).

  7. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    A covalent bond forming H 2 (right) where two hydrogen atoms share the two electrons. A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms.

  8. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    A chemical bond is an attraction between atoms. This attraction may be seen as the result of different behaviors of the outermost or valence electrons of atoms. These behaviors merge into each other seamlessly in various circumstances, so that there is no clear line to be drawn between them.

  9. Molecular orbital - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital

    Complete acetylene (H–C≡C–H) molecular orbital set. The left column shows MO's which are occupied in the ground state, with the lowest-energy orbital at the top. The white and grey line visible in some MO's is the molecular axis passing through the nuclei.
