the three main types of forces - Dipole-Dipole, London Dispersion, and Hydrogen Bonding; identifying relevant types of forces, predicting boiling points
cubic unit cell types - body-centered cubic and face-centered cubic; unit cell calculations; closest packing model patterns - HCP and CCP; crystalline structures of metals and noble gases; crystalline structures of ionic compounds
comparison and characteristics of ionic, metallic, molecular, and covalent network solids; a closer look at the allotropes of carbon; predicting relative melting points of the solids
