Question

What is van der waal forces of attraction?

Answer 1

It enables a gecko to climb even glass smooth objects. No evolutionist can explain how the gecko got the trait.

The amazing ridges on the geckos feet so tiny cause an attractive molecular force. It is not hairs but miniscule ridges.

Answer 2

the net force of attraction between molecules which are non-polar i.e

those in which there is exactly equal sharing of electrons between 2 atoms and none of the bonding atoms possess a relative charge

Answer 3

It is an electrostatic force of attraction between molecules.  Molecules, like atoms, have positive piece (protons) and negative pieces (electrons).  When two molecules are near one another, the electric field of each molecule distorts the other molecule, causing the positive and negative bits to move a bit.  Under this condition, the positive bits of one molecule attract the negative bits of the other molecule, and vice versa, causing the molecules to feel a force of attraction between them.

Answer 4

It's the attraction resulting simply from molecules being close to one another

Answer 5

It's a force that reacts with nano-sized hairs. This is how a gecko clings to glass; the massive amounts of tiny hairs on its feet are affected by this force.
