Brownian motion of sol particles

It is proposed that this article be deleted because of the following concern:

Article is completely redundant to Brownian motion. There is nothing unique about Brownian motion in sol particles as opposed to other particles, and there is nothing here of value to merge. Unsourced for a decade. (proposed by WeirdNAnnoyed)

Colloidal particles in a sol are continuously bombarded by the molecules of the dispersion medium on all sides. The impacts are however not equal in every direction. As a result, the sol particles show random or zig-zag movements. This random or zig-zag motion of the colloidal particles in a sol is called Brownian motion or Brownian movement.

The phenomenon of Brownian motion was observed by Robert Brown in the form of random zig-zag motion of pollen grains suspended in water. This kind of movement is found in all colloidal systems. Such random motion is visible under ultramicroscopes and for bigger particles even under ordinary microscopes.

The Brownian motion becomes progressively less prominent, as the particles grow in size or the viscosity of the medium increases.
