Dispersion Force

Real World Example

Imagine trying to balance a stack of unevenly distributed books on a wobbly table. Much like the shifting weight of the books causes the table to momentarily tilt in one direction, the electrons in an atom can shift, creating temporary regions of positive and negative charge. Just as the table's balance is affected by the shifting weight, the temporary charges in atoms cause weak forces of attraction or repulsion between them, known as dispersion forces.
