  1. van der Waals force - Wikipedia

    https://en.wikipedia.org/wiki/Van_der_Waals_force

    WebIn molecular physics, the van der Waals force is a distance-dependent interaction between atoms or molecules.Unlike ionic or covalent bonds, these attractions do not result from a chemical electronic bond; they are comparatively weak and therefore more susceptible to disturbance. The van der Waals force quickly vanishes at longer distances between …

  2. van der Waals radius - Wikipedia

    https://en.wikipedia.org/wiki/Van_der_Waals_radius

    WebThe van der Waals volume, V w, also called the atomic volume or molecular volume, is the atomic property most directly related to the van der Waals radius.It is the volume "occupied" by an individual atom (or molecule). The van der Waals volume may be calculated if the van der Waals radii (and, for molecules, the inter-atomic distances, and …

    WebWillem Frederik Prins van Oranje-Nassau (Den Haag, 24 augustus 1772 – Berlijn, 12 december 1843) was de eerste koning der Nederlanden uit het huis Oranje-Nassau.. Na de nederlaag van Napoleon in de Slag bij Leipzig in 1813 werd hij ingehuldigd als 'soeverein vorst' der Verenigde Nederlanden.Op 16 maart 1815 riep hij zichzelf uit tot koning van het …

    WebDe Republiek der Zeven Verenigde Nederlanden (Latijn: Belgium Foederatum) was tussen 1588 en 1795 een confederatie met trekken van een defensieverbond en een douane-unie.Ze besloeg grotendeels het grondgebied van het huidige Nederland.Zij verwierf in de 17e eeuw grote politieke en economische macht en speelde geruime tijd een …

  5. Duitse Bond - Wikipedia

    https://nl.wikipedia.org/wiki/Duitse_Bond

    WebDe Duitse Bond (Duits: Deutscher Bund) of Duitse Confederatie was een statenbond met federale elementen. De leden waren ruim 40 Duitse staten. Enkele staatshoofden waren niet-Duitse vorsten, onder andere de Engelse koning die tot 1837 ook koning van Hannover was. Oostenrijk en Pruisen, twee grote Europese machten, lagen deels buiten de …

  6. Chemical bond - Wikipedia

    https://en.wikipedia.org/wiki/Chemical_bond

    WebA chemical bond is a lasting attraction between atoms or ions that enables the formation of molecules and crystals.The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds, or through the sharing of electrons as in covalent bonds.The strength of chemical bonds varies considerably; there are "strong bonds" or "primary …

  7. Covalent bond - Wikipedia

    https://en.wikipedia.org/wiki/Covalent_bond

    WebA covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms.These electron pairs are known as shared pairs or bonding pairs.The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. For many molecules, the sharing of electrons allows each …

  8. Hydrogen bond - Wikipedia

    https://en.wikipedia.org/wiki/Hydrogen_bond

    WebStructural details, in particular distances between donor and acceptor which are smaller than the sum of the van der Waals radii can be taken as indication of the hydrogen bond strength. One scheme gives the following somewhat arbitrary classification: those that are 15 to 40 kcal/mol, 5 to 15 kcal/mol, and >0 to 5 kcal/mol are considered strong, moderate, …

  9. Empty string - Wikipedia

    https://en.wikipedia.org/wiki/Empty_string

    WebFormal theory. Formally, a string is a finite, ordered sequence of characters such as letters, digits or spaces. The empty string is the special case where the sequence has length zero, so there are no symbols in the string.

    https://www.sciencedirect.com/topics/chemistry/van-der-waals-bond

    WebVan Der Waals Bond. Van der Waals bond: A weak attractive force between atoms or nonpolar molecules caused by a temporary change in dipole moment arising from a brief shift of orbital electrons to one side of one atom or molecule, creating a similar shift in adjacent atoms or molecules.
