Maximizing Space The Science of Packing Efficiency

The video tutorial explains packing efficiency in crystal lattices, focusing on simple cubic, body-centered cubic, and face-centered cubic unit cells. It covers the structure, coordination number, and packing efficiency of each type, highlighting the differences in atom arrangement and space utilization. The simple cubic unit cell has a low packing efficiency due to its low coordination number, while the body-centered and face-centered cubic unit cells have higher efficiencies due to better atom packing and higher coordination numbers.
