Document Summary
Count up valence e "s ( group z333,2--30--3. 3--3. 3 4. Match of valence is to of bonds / electrons ctboctl. Polar covalent bond identification and electro negativity look. Labk chart at electronegative. ty most electronegative 5 least electronegative. Lewis structures and electronegativity with charge count up if. Add valences the charge is negative and subtract. 1 if the charge is positive can have unequal # of electrons. Calculate formal charge on each element to determine where the charge goes. Formal charge = ( # of valence ej) - ( unshared is ) - of bonds ) n=s. Move around the bonds or unpaired electrons to shift octets. The resonance formal charge to the has that form correct or the one in which all. Stable octets are atom charged without charge is. Q h foray,eki itin: n" electrons stable because more the. A all octets are satisfied are balanced and. Count of atoms and lone pairs indicated atom is connected to.
