Teaching note for 2018 – move deadlines for LS2 &3 forward a little so the due date is closer to the lesson.
Friday
Materials - whiteboards, markers
Content & Methods
·  Introduction to Lewis structures - molecules with single bonds
a)  Count the number of valence electrons in the molecule. (“Have”, use periodic table to look up the number of valence electrons in each atom. Add these up to find total # of electrons.)
b)  If each atom was unbonded and obeying the octet rule, find the total capacity for electrons. Atoms have a capacity of 8 except hydrogen’s is 2. For example, in H2S, the capacity is 2 + 2 + 8=12
c)  (capacity – have)/2 = # bonds in molecule
d)  Draw the bonds and pairs of electrons.
e)  Check
o  molecule contains the “have” # of electrons
o  all atoms obey the octet rule
