^^^ agreed! also remember that resonance structures do NOT change the number of electrons and bonds it is just a rotation of where the bonds are held (only with areas that have 2 or more bonds). hope this help!

Re: Question 3.55
to clarify, a radical is an unpaired electron... with the exception of those elements that are exception to the octet rule it must complete the octet rule in order to not be seen as a radical (sorry if this is more confusing )!!

Re: Polar covalent bonds & partial charges
it is really helpful to know how to draw the structure of the atom first. The covalent bond is the bond that holds them together. Nonpolar covalent bonds have equal electro negativity therefore on is NOT pulling more than the other due to the atoms evenly sharing (e.g. Florine --Florine). Polar bond...
