WebDefine the following and give an example of each: (a) dispersion force. (b) dipole-dipole attraction. (c) hydrogen bond. (a) Dispersion forces occur as an atom develops a temporary dipole moment when its electrons are distributed asymmetrically about the nucleus. This structure is more prevalent in large atoms such as argon or radon.

Arranging layers of close-packed spheres such that … gift baskets sunshine coastThere are two simple regular lattices that achieve this highest average density. They are called face-centered cubic (FCC) (also called cubic close packed) and hexagonal close-packed (HCP), based on their symmetry. Both are based upon sheets of spheres arranged at the vertices of a triangular tiling; they differ in how the sheets are stacked upon one another.
