How does it do it (what does it do with H+ ions)? - ANSWER-donates or accepts H+
ions
How they form (covalent) - ANSWER-atoms sharing valence shell electrons to balance
Into what structure do they self-arrange? - ANSWER-head and two tails/phospholipid bi
layer
Know how an ionic bond forms - ANSWER-valence shell wants 8 e's, so steals one

TEM - ANSWER-...
Know the example of a triple bond (Triyne) and what it does - ANSWER-share 3
electrons in outer shells
Know the pH scale - ANSWER-scale for # of hydrogen ions in a solution
acidity - basicity
