procedure: for part 1, write the lewis dot (or electron dot) structure for each atom, followed by the ions that each element would form, the compound that would be formed from the combination of the two elements and finally the lewis dot structure for the compound.
for part 2, show the lewis dot structure for each molecules, its axe designation and finally its electron pair/ geometric shape geometries. also indicate any partial charges that may exist on that molecule.

question #1 :
which of the molecules in this exercise have polar bonds, but the molecule itself is non-polar? what makes that molecule(s) non-polar?
you should find nine (9) structures! . remember that a difference of electronegativities greater than 0.1 determines a polar covalent bond, but a symmetrical structure will cancel bond polarity and be a non-polar molecule.
