Question 3

what do you call structures will more than 1 possible LEWIS STRUCTURE

and what symbol to signify

Answer 3

Resonance Structures

double-ended arrows

Question 4

EN values BOND POLARITY

Answer 4

< 0.5 non polar
0.5 - 1.9 polar
> 1.9 ionic

Question 5

RULE for negative formal charges

Answer 5

must be on the MORE ELECTRONEGATIVE ATOM

Question 6

Electron Pair Geometry VS Molecular

Answer 6

EPG = overall arrangement of all e- groups around central atom

MG = arrangement of bonding pairs around

A X E notation meaning

Answer 7

A - central atom
X - # of bonds
E - # of e- pairs
