Asked by Farah
I am asked to draw lewis strcutures of the following molecules and ions
SF6, BrF5, XeF4, PF5 and IF4-.
I have to follow a specific format to draw them, below is an example of SF6, where am i going wrong in the table, since i am not getting six bonds, nor am i successful with the others. Are they an exception to the octet rule and cannot calculate them that way?
Valence Electrons 6e- + 42e- = 48e-
Noble gas Config 8e- + 48e- = 56e-
Total 56e- - 48e- = 8e-
Covalent bonds 8e-/2 = 4
Non-Bonding Pairs 48e- - 8e- = 40e-
Help please!

I believe all are exceptions.
See this link. Go to page 8 for SF6. The others may be there too but I didn't look. http://www.smallscalechemistry.colostate.edu/PowerfulPictures/LewisDiagrams.pdf
