What is a good way to double check that all of your calculated formal charges are correct?
al formal charges must equal the real charge of the molecule
formal charge= valence electrons- 1 per bonding pair- number of lone pairs
Does the best Lewis structure have the highest or lowest magnitude of formal charges?
change in energy when an ionicsolid turns into gas phase ions
Based on Hess's Law, what is the Born-Haber cycle?
allows use to calculate lattic energy based on hess's law
high melting points
Explain how the atomic radius depends on the number of electrons
cation will be smaller& anion will be larger than neutral atom
with cation (electrons pulled in towards core more bc of more positive charge) vice versa with anions
number of pairs of bonds in a structure (single bond, double bond, etc.)
