Waalskreftene
Waalskreftene, also known as van der Waals forces, are weak intermolecular forces that exist between all atoms and molecules. They are named after the Dutch physicist Johannes Diderik van der Waals, who first described them in the late 19th century. These forces are responsible for many physical properties of matter, such as surface tension, viscosity, and the boiling and melting points of substances.
There are two main types of van der Waals forces: London dispersion forces and dipole-dipole interactions. London
Van der Waals forces are relatively weak compared to other types of intermolecular forces, such as ionic
In summary, van der Waals forces are weak intermolecular forces that exist between all atoms and molecules.
