A molecule of ammonia, NH3, and a molecule of methane, CH4, each have 4 electron domains.
a.) Draw or describe the Lewis dot structures for each of these molecules.
b.) Explain why the bond angles are different for these two molecules.
Use the principles of bonding and molecular structure to explain the following statements:
a.) The boiling point of argon is -186°C whereas the boiling point of neon is -246°C.
b.) Solid sodium melts at 98°C but solid potassium melts at 64°C.
c.) More energy is required to to break up a CaO(s) crystal into ions than to break up a KF(s) crystal into ions.
d.) Molten KF conducts electricity but solid KF does not.
