Question
The Kapustinskii equation can be used to calculate this quantity. For 10 points each:
[10h] Name this quantity, the energy released during the formation of a crystal. It can also be calculated from the Born-Haber cycle.
ANSWER: lattice energy [accept lattice enthalpy]
[10e] The lattice energy measures the strength of these bonds. They are contrasted with covalent bonds.
ANSWER: ionic bonds
[10m] The lattice energy is inversely proportional to the “ionic” form of this quantity. Another form of this quantity increases as one goes left across the periodic table.
ANSWER: radius [accept ionic radius; accept atomic radius]
