We discussed the reason for the trends in atomic radius, ionization energy, and electron affinity, using the handout "trend explanations" found on the unit 1 page of this site.  Consult p.52, 55, 58 for help with this explanation.
We also discussed how ionic compounds form, using Bohr diagrams, and using Lewis diagrams.  The handouts used, "ionic comp handout" and "Lewis diag handout" are downloadable from the unit 1 page of this site.  Consult the text p.75-78 for help.
Homework:  Complete the questions on the Lewis symbol handout and answer p.46 #6 and p.78 #5.
