3/11 – Friday – A Day – 2/3a Lab, 4
a) To interpret a potential Energy Internuclear Diagram in terms of bond energy and bond lengths.
b) To identify the factors that contribute to the strength of Lattice constants.
4: Lattice Energy – Lets Remember that we have ionic compounds that are in the mix. They are ions attracting themselves in a crystal lattice and are not part of the hybridization or polarity discussion. Because all ionic compounds are solids (in crystal arrangements) at STP we use lattice energy to describe their stability or strength of ionic character. Much like we use the difference of electronegativity for the dipole moment of each polar bond in covalent (molecular) compounds.
5. Limitations of valence bond theories.
