The first is the subatomic level, which studies the atom individually and the behavior of its nucleus and electrons. The second level is the atomic level, which studies the interaction between several atoms and the formation of bonds and molecules. The third level is the microscopic level, which corresponds to the atomic and molecular arrangements and the formation of crystalline, molecular, and amorphous structures. Finally, the macroscopic level relates to the material's behavior in service. (CALLISTER JR., W. D.; RETHWISCH, D. G. Materials Science and Engineering: An Introduction. 8th ed. Rio de Janeiro: LTC Publisher, 2013).
