Learning Objectives Understand how valence electrons participate in covalent bond formation. Given the Periodic Table, be able to predict how many bonds an element can form. Be able to distinguish the types of strong bonds (covalent) based on electronegativity. Differentiate strong bonds from weak bonds (charge interactions). Be able to distinguish the types of weak bonds (ionic, hydrogen, hydrophobic / van der Waals). Know what elements can participate in hydrogen bonding. Understand why dynamic living systems depend on weak bond interactions. Know how hydrogen bonding influences the properties of water: heat capacity cohesion density hydration Be able to predict the behavior of hydrophilic, hydrophobic and amphipathic substances in water. Understand how autohydration of water is related to pH. Be able to roughly estimate the pH of various common materials.
