ENGR 54 – Principles of Materials Science and Engineering: Lecture 02 2 Today Discussion on Structure of Materials Atomic Structure and Bonding Reading assignment: Through Chapter 3
ENGR 54 – Principles of Materials Science and Engineering: Lecture 02 3 The Structure of Materials There are many facets of the structure of materials One facet relates to the chemical composition of the material: Atoms are the fundamental building blocks of materials . Chemical interactions, resulting in the formation of bonds that result from the electronic structure of the atoms, play a critical role in determining the structure an properties of materials. This tendency for atoms to bond to one another gives rise to the condensed phases of matter – liquids, glasses, crystals, quasicrystals and liquid crystals – that we generally refer to as materials.
