A linear Reason One-dimensional Closed Packing

The video tutorial explains the packing arrangement of crystals, where particles are assumed as solid spheres to maximize space and density. It introduces the concept of coordination number, which is the count of nearest neighbors around a particle. The tutorial covers three types of packing: one-dimensional, two-dimensional, and three-dimensional, with a focus on one-dimensional packing where each particle contacts two neighbors, resulting in a coordination number of two.
