Document Summary

Meen 222 textbook notes: chapter 2, quantum numbers i. ii. iii. iv. Spin (+ or - : electronegative i. ii. Readily accept electrons to form negative ions: bonding forces i. ii. iii. iv. v. Ro, equilibrium spacing, minimum point of net energy curve. Eo, bonding energy, the energy at that minimum point. Hybridization, the mixing of two or more atomic orbitals: secondary bonding i. ii. Weak in comparison, arise from dipoles: dipoles are created when there is an uneven split of positive and negative charge, causing brief coulombic attraction iii. Polar molecules: permanent dipoles due to asymmetrical arrangement of charge, have the ability to induce dipoles in other molecules, chapter 3, crystalline material i. ii. Atoms are situated in a repeating or periodic array over large atomic distances. Materials than don"t crystallize are called nanocrystalline or amorphous: atomic packing factor (apf) i. (volume of atoms in a unit cell) / (total unit cell volume) c.
